feat(v0.2.6): add const/variable cross-reference tracking and same-file usage detection

- Add const_item/static_item to Rust extract_exports, const_spec/var_spec to Go
- Track all variables (not just exported) for same-file usage in scanner
- Split query output into usedAt (local) and importedBy (cross-file) sections
- Fix Python export fallback dedup, fix format_symbol_results display for local refs
- Bump version to 0.2.6
