* fix(SM-15): address all PR #763 review findings

Performance (R1)
- Changed _fileScopeByFile from Map<string, [string,string][]> to
  Map<string, Map<string,string>>. fileScopeGet(filePath, name) is
  now O(1) — replaces the O(n) linear scan + defensive-copy alloc
  that ran once per ConstructorBinding entry. fileScopeEntries()
  reconstructs tuples from Map.entries() for backward compat.
- Updated finalize() dev-mode invariant to compare deduplicated Map
  size rather than raw array length (Map.set deduplicates same-name).

Lifecycle (R2)
- Documented that Phase 9 intentionally reads pre-finalize because
  finalize() cannot move before both the worker consumer (line 984)
  AND the sequential-path writer (line 1061). Pre-finalize reads are
  safe because finalize() is write-lock-only with no side effects.
  Replaced the ambiguous "populated but not yet finalized" comment
  with the full lifecycle ordering explanation.

Sequential-path parity (R3)
- Wired bindingAccumulator into processCalls at line 797 (sequential
  path) so verifyConstructorBindings gets the Phase 9 fallback.
- Added bindingAccumulator parameter to processAssignmentsFromExtracted
  signature and wired it at the pipeline.ts call site (line 1026).
- Both paths now produce identical Phase 9 behavior for the same code.

Tracking comments (R4)
- Added "Overlapping mechanism (N of 3)" cross-references at:
  1. buildImportedReturnTypes (~line 109)
  2. collectExportedBindings (~line 168)
  3. Phase 9 fallback in verifyConstructorBindings (~line 563)
  Each links to the other two and notes future unification.

Language coverage (R5)
- Added 5 new Phase 9 integration test suites in cross-file-binding.test.ts:
  JavaScript, C++, C#, PHP, Ruby. Each uses the existing fixture
  directories and asserts getUser() → User → user.save() resolves.
  Total cross-file binding tests: 52 (was 37).

Quality asymmetry (R6)
- Added inline comment at the Phase 9 fallback noting worker-path
  entries are Tier 0/1 only and that binding accuracy is structurally
  lower for large repos where the worker path dominates.

Tests (+21 new)
- 6 fileScopeGet unit tests (happy path, unknown file/name, mixed
  scopes, post-dispose, duplicate varName last-write-wins)
- 15 integration tests across 5 new language suites

Verification
- tsc --noEmit clean
- 3147 unit tests pass (+6 new)
- 52 cross-file binding integration tests pass (+15 new)
- 1766 resolver integration tests pass
- Zero regressions

* fix(SM-15): gate accumulator fallback on resolution tier and fix sequential file-order dependency

Two Codex adversarial reviews identified medium-severity bugs in the Phase 9
BindingAccumulator fallback:

1. Local-first violation: the fallback fired regardless of whether ctx.resolve()
   found same-file candidates, letting an imported callee shadow a local one
   and produce false CALLS edges. Fixed by gating on tiered.tier !== 'same-file'
   and callableDefs.length <= 1.

2. Sequential file-order dependency: processCalls flushed and verified per-file,
   so consumer files processed before their providers missed accumulator bindings.
   Fixed by splitting into a flush pre-pass (all files) then a resolution loop,
   mirroring the worker path's "all appends before any reads" pattern.

Also adds 11 consumer-before-provider integration test fixtures (one per
supported language) and 4 unit tests for tier gating edge cases.

* refactor(SM-15): eliminate duplicated prepare logic in processCalls two-pass split

Replace the duplicated pre-pass + legacy-path code (parse → query → heritage
→ TypeEnv → exports) with a single preparation loop followed by a resolution
loop. Both paths now share the same preparation code — the only conditional
is the accumulator flush.

Side benefit: globalParentMap is now fully populated before any resolution
runs, improving cross-file isSubclassOf accuracy regardless of file order.

Net -118 lines (226 removed, 108 added).

* fix(SM-15): address PR #763 third-pass review findings

1. Update stale dispose() JSDoc — remove forward-reference to Phase 9
   wiring that is now complete; document actual consumers.

2. Add processAssignmentsFromExtracted Phase 9 unit test — verifies the
   accumulator fallback produces ACCESSES write edges when the SymbolTable
   has no returnType for the callee.
