fb20a3c752 feat: implement cross-file binding propagation for multiple languages 
- Enhance C++ tree-sitter queries to support inline class method declarations and return types.
- Introduce `importedRawReturnTypes` in `BuildTypeEnvOptions` for cross-file raw return type handling.
- Add `FileTypeEnvBindings` interface to capture file-scope type bindings for exported symbols.
- Implement logic in `parse-worker.ts` to extract and serialize file-scope type bindings for cross-file type resolution.
- Create test fixtures for C++, Go, Ruby, and Rust to validate cross-file binding propagation.
- Update integration tests to verify correct resolution of method calls across files for C++, Go, Ruby, and Rust.
- Document Phase 14: Cross-File Binding Propagation in the type resolution roadmap and system documentation.

6c972079e0 feat(type-resolution): per-language cross-file binding tests + resolver fixes 
Add cross-file binding propagation integration tests for 6 languages
(Python, JavaScript, Java, PHP, C#, Kotlin) with fixture repos and
HAS_METHOD edge assertions.

Fix 3 language resolver issues uncovered by tests:
- Kotlin: class methods now labeled Method (not Function) via shared
  isKotlinClassMethod() utility; non-aliased imports create NamedImportMap
  entries; 2-segment package-directory fallback for top-level function imports
- PHP: namespace-directory fallback for use-function imports; SuffixIndex
  preferred over linear scan; path traversal rejection; PSR-4 sort cached
- JVM: root-level package path matching; indexOf→lastIndexOf for correctness

Address code review findings:
- Extract runCrossFileBindingPropagation() from 810-line pipeline function
- Replace (importCtx as any) casts with typed dispose() method
- Remove Tarjan's SCC (dev-only YAGNI, ~85 lines)
- Remove dead PARALLEL_RE_RESOLUTION_THRESHOLD constant
- Fix constructor handling divergence in getLabelFromCaptures
- Optimize gap pre-scan with early exit once threshold exceeded
- Fix findEnclosingFunction any→SyntaxNode type

fff716dd92 feat(type-resolution): Phase 14 enhancements — single-pass seeding, Tarjan's SCC, cross-file return types 
E0: Fix AST cache thrashing in re-resolution loop (was creating size-1
cache per file), batch file reads per topological level, add
MAX_CROSS_FILE_REPROCESS=2000 cap for adversarial repos.

E1: seedCrossFileReceiverTypes() — enrich ExtractedCall.receiverTypeName
from ExportedTypeMap+namedImportMap in O(1) Map lookups, eliminating
re-parse for ~80-90% of single-hop cross-file receiver types.

E2: computeImportCycleSCCs() — iterative Tarjan's SCC on cycle subgraph
from Kahn's output. Dev-mode diagnostic logging of individual import
cycle components.

E3: buildImportedReturnTypes() + ReturnTypeLookup extension — cross-file
return type propagation with corrected local-first priority (SymbolTable
checked first, cross-file fallback only on 0 matches, ambiguous 2+
returns undefined).

E4: PARALLEL_RE_RESOLUTION_THRESHOLD constant, timing metrics, worker
parallelization design comments (deferred implementation).

24 new tests (6 E1 + 6 E2 + 7 E3 unit + 5 E3 integration). All 3478
tests pass.

a6a1004e82 feat(type-resolution): Phase 14 — cross-file binding propagation 
Add ExportedTypeMap infrastructure to propagate resolved type bindings
across file boundaries. When file A exports `const user = getUser()`
(resolved to `User`), file B importing `user` now gets seeded with
`user → User`, enabling `user.save()` to produce CALLS edges.

Key components:
- `importedBindings` option on BuildTypeEnvOptions with scopeEnv seeding
  AFTER walk() to respect first-writer-wins (local declarations win)
- `collectExportedBindings()` in call-processor using graph node
  isExported flag (no SymbolDefinition changes needed)
- Inline Kahn's algorithm topological sort with level grouping for
  parallel-safe file ordering and cycle detection
- Re-resolution pass in pipeline.ts: topological order, 3% skip
  threshold, path validation, per-file export caps (500)
- 32 new tests: 11 topological sort, 6 seeding, 15 integration
  (simple cross-file, re-export chain, circular imports)

All 3454 tests pass (32 net new, 0 regressions).
