fix(graph): retain Rust implementation method identities

[DivyamTalwar]

Summary

Fixes #437.

The Rust call pass chooses an enclosing function by name rather than its declaration, so same-named methods on different types can share the wrong caller. Owner edges also assume a class-shaped plain impl type, missing generic and enum ownership and collapsing same-named trait methods.

Track each represented callable by source position, preserve complete implementation type spelling in method IDs, and distinguish trait implementations with a type-and-trait-qualified identity. Resolve method ownership to locally declared structs/enums after declaration collection. Preserve constant-generic literal bytes and reject speculative owner links for unsupported scoped/reference types.

Version Bump

No release requested. Package versions, dependencies, lockfiles and release workflows are unchanged.

Test plan

• Repository-native regressions against unchanged production source: 14 failed, 16 controls passed, zero skipped.
• Corrected focused suites: 30 passed, zero failed or skipped, plus local typechecking.
• Exact submitted commit 6a9a1942f80f23b17899b8143510e478971b1ba7: independent Node 22/Linux full suite with coverage, 5,864 passed, zero failed, zero skipped. The same job passes typecheck, production build, duplication guard, critical-only bundle audit and diff checks.

Exact checkout, commands, full-suite results and retained logs. Each branch was validated independently. Tests use synthetic code/transcripts and isolated filesystem fixtures, not live model calls or user data.

Compatibility and limits

Type aliases, Self, imported/cross-file owners and semantic type equivalence are not resolved. Existing inline-module item IDs remain flattened, so this is not a complete module-identity redesign. Trait method IDs intentionally change to distinguish implementation histories; inherent nongeneric IDs remain unchanged. Calls inside unrepresented closures are left unresolved rather than credited to the outer function. Textual type spelling is preserved, not normalized by a Rust type checker.

The current open-PR file inventory and issue titles were checked before submission. A clean full macOS suite or native Windows execution is not claimed. The independent gate does not replace upstream CI or maintainer review.
