refactor(app): extract typed RuntimeOptions for startup env vars (Step 1)

Browse source 
Lifts 13 startup-time environment variables out of GameWindow.cs into a
single typed AcDream.App.RuntimeOptions record read once in Program.cs.
Behavior-preservation only — no live behavior change, no visual change.
Verified end-to-end against ACE on 127.0.0.1:9000: full M1 demo loop
(walk Holtburg, click door, click NPC, portal entry) plus DEVTOOLS
ImGui panels load cleanly.

Why: GameWindow.cs is 10,304 LOC and scattered Environment.GetEnvironmentVariable
calls were one of the structural smells called out in the new
"Code Structure Rules" doc. Typed options is the safest cut to make
first because the substitution is mechanical and parsing semantics
get pinned by unit tests.

What lands:
  - CLAUDE.md: removed stale R1→R8 execution-phases line, replaced with
    pointers to the milestones doc + strategic roadmap (the actual
    source of truth). Tightened the "check ALL FOUR references"
    section to describe WB as the production rendering base, not
    just a reference. New "Code Structure Rules" section (6 rules)
    captures the discipline we're committing to.
  - docs/architecture/acdream-architecture.md: removed dangling link
    to the deleted memory/project_ui_architecture.md.
  - docs/architecture/code-structure.md (NEW, 376 LOC): rationale for
    the 6 rules + 6-step extraction sequence
    (RuntimeOptions → LiveSessionController → LiveEntityRuntime →
    SelectionInteractionController → RenderFrameOrchestrator →
    GameEntity aggregation). This PR is Step 1.
  - src/AcDream.App/RuntimeOptions.cs (NEW, 100 LOC): typed record
    with FromEnvironment(string) factory and Parse(datDir, env)
    overload for testability. Covers ACDREAM_LIVE, _TEST_HOST/PORT/
    USER/PASS, _DEVTOOLS, _DUMP_MOVE_TRUTH, _NO_AUDIO,
    _ENABLE_SKY_PES, _HIDE_PART, _RETAIL_CLOSE_DEGRADES,
    _DUMP_SCENERY_Z, _STREAM_RADIUS.
  - src/AcDream.App/Program.cs: builds RuntimeOptions once, passes
    to GameWindow.
  - src/AcDream.App/Rendering/GameWindow.cs: ctor takes RuntimeOptions;
    7 startup-cached env-var fields become expression-bodied
    properties or direct _options.X reads; TryStartLiveSession,
    audio init, legacy stream-radius branch all route through
    _options.
  - tests/AcDream.App.Tests/ (NEW project, 10 unit tests + csproj):
    pins parser semantics — default-off bools, the literal "0"
    gate for RETAIL_CLOSE_DEGRADES, the >=0 guard for
    STREAM_RADIUS, null-vs-empty for user/pass, exact-"1" check
    for diagnostic flags. Registered in AcDream.slnx.

Out of scope (per code-structure.md §4):
  - Per-call-site ACDREAM_DUMP_* / _REMOTE_VEL_DIAG diagnostic reads
    sprinkled through GameWindow (~40 sites). Rule 5 in CLAUDE.md
    commits us to migrating these opportunistically as larger
    extractions land, not in a bulk pass.
  - AcDream.Core's project-reference to Chorizite.OpenGLSDLBackend.
    Only the stateless .Lib namespace is used; tightening the project
    reference is documented as future work in code-structure.md §2.

Build: green.
Tests: AcDream.App.Tests 10/10 ✓, Core.Net.Tests 294/294 ✓,
       UI.Abstractions.Tests 419/419 ✓,
       AcDream.Core.Tests 1073/1081 (8 pre-existing failures verified
       against pre-refactor baseline by stash-and-rerun).

Visual verification: full M1 demo loop against ACE +Acdream login
including DEVTOOLS panel host load.

Next: Step 2 — extract LiveSessionController per code-structure.md §4.
