Gergo Magyar 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
