fix #435 (part 2, closes it): attribute the unowned probes — delete 7, reclassify 8, restore 1

Part 1 deleted probes whose owning issues were closed. These 14 named no issue at all, so each was traced to its introducing commit (git log -S) instead of guessed at. Attribution split them three ways: DELETED (7, investigations closed): ACDREAM_A8_DUMP_PV and ACDREAM_DUMP_LIVE_SPAWNS (Phase A8), ACDREAM_DUMP_CLOTHING (#37), ACDREAM_DUMP_EDGE_SLIDE (#32), ACDREAM_DUMP_STEPUP (L.2.3d-f), ACDREAM_DUMP_VENDOR (the vendor campaign, 25 call sites across 8 files), ACDREAM_DUMP_VITALS (#5, four independent read sites). VendorDiagnostics.cs went entirely. RECLASSIFIED (8, tools misfiled as probes): the DUMP_CELLS/DUMP_GFXOBJS fixture-extraction family (replay-harness tooling with a roundtrip test), PROBE_CELL (standing cell-transit tracer, pair of the permanent PROBE_RESOLVE), DUMP_SKY and HIDE_PART (generic isolation tools), and DUMP_STEEP_ROOF — which looked like an L.4 relic but observes LIVE divergence-register row AD-56; deleting it would have removed the only runtime lens on an active divergence. All moved to Permanent diagnostics with their attribution recorded. RESTORED (1): ACDREAM_DUMP_MOVE_TRUTH was deleted and un-deleted the same day. It is not a probe — the canonical nine-stop soak (run-connected-r6-soak.ps1) hard-fails every destination without its 'move-truth OUT' records, with a message that would misdirect the next operator. Under the no-workarounds rule the gate's mechanism is restored, not left broken with an IOU (#437, closed). Process lesson recorded on both issues: a closed owning issue is NOT sufficient to delete a probe — grep tools/ and the contract tests for consumers first. Also lands the owner-requested default-off invariant: every diagnostic in the codebase is inert until its env var is explicitly set. Exactly four flags default ON and none is a diagnostic — RETAIL_CHASE, CAMERA_COLLIDE, CAMERA_ALIGN_SLOPE, RETAIL_CLOSE_DEGRADES are retail behaviors wearing an A/B off-switch. That set is now FROZEN by LaunchOptionsDocumentationTests.OnlyTheFourRetailBehaviorFlagsDefaultOn; docs/launch-options.md's Conventions and CLAUDE.md state the rule, and CLAUDE.md now binds future probes to a documented row in the same commit. The client reads 137 environment variables (161 at audit start); 40 temporary probes remain, every one attributed. Full hermetic suite 15,322 passed / 0 failed.
