merge(vt): bring in retail scrollbar chrome + resizable/anchor markup

Merges claude/latest-main-sync-497549 into the slice-7 panel worktree
so round D can build on both: b71a8ea37 (retail scrollbar chrome on
plain <menu> popups and overflowing <list>s — chat/inventory sprite
ids, always-scrollable single-column menu) and 2e63391cc (<panel
resizable minw minh> + anchor="left top right bottom" markup).

Conflicts resolved keeping both intents:
- Ledger (docs/plans/2026-09-07-campaign-vt-slice7-tabs.md): unioned
  both branches' entries into one chronological timeline instead of
  picking a side.
- docs/plugin-ui-markup.md: kept both attribute additions per element
  (slider min/max/style, menu scroll/style) AND anchor on every row.
- src/AcDream.App/UI/UiMarkupList.cs: kept this branch's fix round B
  item 10 (VVS HudList grids have no row-selection highlight) over the
  sync branch's older SelectedColor band draw in the <column> grid
  path — the legacy single-column list path is unaffected either way.
- src/AcDream.App/UI/MarkupDocument.cs: the auto-merge left two
  `Scrollable =` initializers on the same <menu> object (CS1912).
  Kept the sync branch's `Scrollable = true` (VTank's HudCombo is
  always a single scrolling column, never a wrapping grid) and
  dropped this branch's `Scrollable = B(el, "scroll", false)` opt-in,
  since the owner-driven always-scrollable design supersedes the
  S7.2 opt-in one. Updated MarkupDocumentTests.cs to match: removed
  Build_MenuWithNoScrollAttribute_KeepsScrollableFalse (asserted the
  now-false opt-in default) and
  Menu_Scroll_DrawsAPlainFlatThumbFillWhenTheMarkupItemCountOverflowsTheVisibleRows
  (asserted a flat DrawFill thumb; the scrollbar is sprite-chrome for
  every menu style now) — both fully superseded by
  Menu_Markup_IsAlwaysScrollable_WithRetailScrollbarChromeWired and
  UiMenuPlainStyleTests.Plain_OpenPopup_ScrollableOverflow_
  DrawsRetailScrollbarChrome_RowsStayPlain.

Verified: dotnet build AcDream.slnx -c Release green; MossTank suite
678/678; App markup/plugin filter 242/242 (241 before this commit's
test-file trim, +1 net from the merge's own new tests, 0 red).

+- 2026-09-07 owner asked whether every VTank format should get a human-readable twin like `.af`. Lead's answer, recorded as a post-campaign idea: VTank's `.usd`/`.ugd`/`.utl`/`.met` are already text (the one-value-per-line table grammar) and `.nav` is plain lines; only metas/navs had a community-authored readable format (metaf) with a converter both ways, which is why `.af` is safe as storage. For settings/loot a second format would be our own invention with two sources of truth. Instead: a one-way readable EXPORT + a profile DIFF command (`/vt settings export`, `key = value` lines) for inspection and version control, VTank's format staying the only storage. Revisit only if hand-editing loot rules becomes routine.

-- 2026-09-07 fix round C item F13 folded the `EveryInteractiveControlDeclaresARealHandlerBinding` test's exact-control-count history here, in the same commit that removed it from the test file: Round 3 item 10 added +3 for the Route/Loot/Meta Delete buttons (Settings already had one from round 2 step 5). Campaign VT slice 7 S7.1/S7.2 transcribed Options/Profiles/Vitals control-for-control from VTank's own tabs (docs/research/vtank-kb/08-ui-views.md §1) and repositioned the Advanced Options/Loot Editor popups to VTank's exact 392x300/268x300 geometry — net 194 → 205. The Options tab gained four direct checkboxes for settings that already existed but were only reachable through the generic Advanced Options key-value editor (Enable Autostack, Fastcast Buffs, Don't Shoot at Walls, Fallback Debuffs if Blocked); the Profiles tab gained a real Meta-profile combo/CopyTo row (previously a stub label) and per-type name fields/New buttons, and lost the Loot Priority Boost toggle as a duplicate of the Options-tab control of the same name; the Loot Editor popup lost LootEditorNotice (a status label, not an action). S7.3 replaced the whole Monsters tab body with VTank's own 23-column grid: the select-then-edit surface (1 list + 1 field + 8 buttons + 3 menus + 14 toggles + 3 equip buttons = 30 controls) is gone, replaced by 1 list + 23 columns + 1 field + 2 buttons (27) — net 205 → 202. Fix round A (2026-09-07) moved the Advanced Options and Loot Editor groups OUT of mosstank.xml entirely into their own plugin panels and deleted the Profiles tab's three stacked name-draft field+"New"-button rows and the acdream-only "Loot engine" classifier menu — net 202 → 167. S7.4 replaced the Items tab's single-column list with VTank's own clWeaponName/clHandedness 2-column grid (+2), added the Consumables tab's "Excluded Scarab Types" 2-column grid plus its "Add Selected" button (+4), and added the Buffs tab's Extra Buff Spells / Blacklisted Buff Families lists plus their two "Add..." buttons (+4) — net 167 → 177. S7.5 replaced the Route tab's single-column waypoint list with VTank's own clWP/clWPc 2-column grid (+2) and added the "Select Nearest Point" button (+1) — net 177 → 180. S7.6 replaced the Meta tab's single-column rules list with VTank's own 6-column lstMetaRules grid (+6) — net 180 → 186. Fix round B item 5: VTank's real Meta tab is only 5 controls (the grid, "Create", a caption, and the settable current-state menu). Removed entirely: the profile toolbar (menu/name-draft/New/CopyTo/Clear/Delete, 6) and "Enable Meta" (1) — 7 controls gone for good. Moved into mosstank-metaeditor.xml (a separate file this test doesn't scan): the State/Condition/Action editor (2 fields + 2 menus + 1 field for state + 1 secondary-text field + 4 numeric-stepper buttons + Apply/Remove/MoveUp/MoveDown, 14). Added: the settable cmbMetaCurrentState menu (+1). Net 186 → 166 (-7 -14 +1). Fix round B item 8: the Route tab collapses to VTank's own 2-across button grid + bottom nav-control row, 28 → 18 interactive controls within mosstank.xml. Checkpoint/Jump/Remove/Set Follow Target/Follow Corners/Open Doors/Nav Priority/the Follow-Nav-Min-Distance stepper moved to mosstank-advanced.xml's own new "MossTank Extras" section. The 2-state ToggleRouteAddPosition button became the real 3-option cmbNavInsertMode `<menu>`, and the pause "-"/"+" stepper became one editable field. Net 166 → 156 (the count the test asserted immediately before this fix round removed the assertion). The test's own per-control handler/enabled loop remains the live guarantee; a bare `Assert.NotEmpty(controls)` guards the selector itself.
+- 2026-09-07 11:20 S7.4–S7.6 landed on the panel worktree (`f5409530f` Items/Consumables/Buffs + buff picker popup, `6118062a7` Route grid, `cc323f6a5` Meta grid, `41fc1d88d` screenshots; MossTank suite 654 → 660); the plain popup merged in at `dbdde0783`. Both Opus lenses dispatched on the whole slice. Lead's read of the new Route and Meta screenshots for fix round B: VTank's Route tab is the waypoint list + one small row under it (nav-type menu, insert-mode menu, three icon buttons) + the right-hand Add grid — ours still carries MossTank-only controls on the tab (Checkpoint / Jump / Remove / Set Follow Target / Follow target / Nav Priority / Follow Corners / Open Doors / Use NPC / Follow-Nav Min Distance spinners; "Add to End" rendered as a button instead of the insert-mode menu) that VTank does not show there — move them out (Advanced Options popup, or drop what VTank has no equivalent for). VTank's Meta tab is the six-column grid + Create + "Current State:" menu — ours adds a profile row (By char / New / CopyTo / Clear / Delete / Enable Meta / State) that belongs on Profiles, and an INLINE rule editor (state, condition/action menus, three fields, N/N2 spinners, Apply/Add/Remove, arrows) where VTank opens a separate rule-editor view on click — make it a popup panel like the buff picker. Implementer deviations to judge: Hands column session-local; extra/blacklisted buff names stored but not consumed by the plan; recall menu 4 kinds vs VTank's 27; "Select Nearest Point" moves the edit selection; Meta delete cell is a text "X".
+- 2026-09-07 12:00 both Opus lenses on `dbdde0783`. Resemblance: APPROVE-WITH-FIXES — Options, Vitals and the buff picker read as VTank; Monsters one header fix away; Buffs (VTank's two lists shrunk for a MossTank block, a new "+"/"Add…" overlap) and Meta (grid buried under a toolbar and an inline editor; "Current State:" not settable) do not read as VTank; clipped status lines on three tabs + the Loot Editor; "CopyTo" overflowing its button; Route's grid re-flowed 3-across with "Add NPC Talk" renamed and the nav icons moved; the gold slider track; the 4-vs-27 recall menu is a data hole (slice 6). Owner complaints 1 and 2 closed on the screenshots; 3 closed in code but needs a dropdown-open re-capture. Architecture: APPROVE-WITH-FIXES — one RED App test at HEAD (the `<menu scroll>` sprite pin invalidated by the plain popup merge; the ledger's 192/192 was stale), `ExcludedComponentIcons` captures the whole inventory per row per frame, derived columns allocate per frame, the markup file list hardcoded in four places, the buff lists look live but are neither consumed nor persisted, two host defects found live (filed as #490), the `MarkupDocument.Build`-over-real-files seam untested. Lead decisions for round B: VTank's own controls never shrunk/moved for MossTank extras (extras → Advanced Options popup or dropped); plain sliders; no grid selection band; the Meta rule editor as its own popup; the four Deletes stay, aligned. #491 filed for the buff-list wiring (slice 4). Fix round B (18 items) dispatched.
+- 2026-09-07 14:50 fix round B landed 16/18 on the panel worktree (`040d5f3d8`…`8d3c6ad7c`; MossTank suite → 676, App markup/plugin filter 285/3 skipped); the agent was stopped after three hours failing the screenshot step (malformed session config, disk-wide search) — nothing lost, tree clean. Item 16 was the dedupe, tab-switch popup cleanup, and slider validation. Architecture narrow re-check at `8d3c6ad7c`: NOT merge-ready — D1 the Advanced Options popup re-materializes the 163-entry catalog per frame (the class item 12 killed elsewhere), D2 `/mt refresh` mutates Rules without `RefreshMonsterEditor()`, D3 the bottom-band pin skips unsized children; carried nits (hands column per frame, popup-size theory hardcoded, #491 not cited, mutable bool[]). Fix round C dispatched. Screenshots: replaced by the owner testing LIVE from the gate build at `8d3c6ad7c` (all five plugin windows load); the owner's findings feed round C/D; the resemblance re-check runs on the final state.
+- 2026-09-07 15:20 OWNER LIVE LOOK at `8d3c6ad7c` (gate build): "Looks mostly fine, a lot of polish can be done though. But we do that later." Findings: (1) Advanced Options' category filter shows the raw bitmask values (0x1, 0x2, …) with lamps instead of the category NAMES (Misc, Recharge, MeleeCombat, SpellCombat, Ranges, Navigation, Buffing, Crafting, Looting); (2) Advanced Options must follow VTank's model (owner's screenshots 2/3): name + value columns, clicking a bool/enum VALUE flips it in place, only NUMBERS open the edit field at the bottom (Enter applies) with the description box under it, no Apply/Back buttons; (3) scrollable dropdowns and the popup windows use the SAME scrollbar/window assets as the chat and inventory windows (not the flat scrollbar); (4) the whole window: larger default size AND resizable (window-manager resize like chat, lists stretching); (5) Route's Add Recall is missing most of VTank's recalls and recalls do not work in routes yet. Dispatched now (App side, own worktrees): retail scrollbar assets for plain popups/lists; resizable plugin panels + `anchor` markup. Queued on the panel worktree after fix round C: Advanced Options model + category names; the full VTank recall table with spell ids (metaf `NRecall`, py:10981-11008 — 26 spells: Primary Portal Recall 48, Secondary 2647, Lifestone 1635, Lifestone Sending 1636, Portal Recall 2645, Aphus 2931, Sanctuary 2023, Singularity Caul 2943, Glenden Wood 3865, Aerlinthe 2041, Mount Lethe 2813, Ulgrim's 2941, Bur 4084, PtOIA 4198, Mhoire Forge 4128, Colosseum 4213, Facility Hub 5175, Gear Knight Camp 5330, Neftet 5541, Return to the Keep 4214, Rynthid 6150, Viridian Rise 6321, Viridian Rise Great Tree 6322, Celestial Hand 6325, Radiant Blood 6327, Eldrytch Web 6326) wired to the existing recall execution; adopt anchors + the larger default.
+- 2026-09-07 16:10 App-side pieces merged into the campaign branch: `b71a8ea37` retail scrollbar chrome on plain `<menu>` popups and overflowing `<list>`s (chat/inventory skin ids `0x06004C5F`/`6C`/`69`/`60`/`63`/`66`; markup menus are one-column scrollable), `2e63391cc` `<panel resizable minw minh>` + `anchor="left top right bottom"` on every element (window-manager resize + persistence already generic). App markup/menu/list/window/anchor filter 294/1 skipped. Panel round D (after fix round C on the panel worktree): merge the campaign branch in, Advanced Options model + category names, VTank's 26-recall table wired, `resizable="true"` + anchors on the main panel with a larger default.
