What's New

Rust and Go structural indexing — The codebase indexer now parses Rust and Go files using regex-based annotators with comment/string-aware brace counting. No new dependencies.

Go Support

• Function and method declarations (including generic functions)
• Struct types with embedded type detection
• Interface types with method signature extraction
• Type aliases
• Single and grouped imports (aliased, dot, blank)
• Doc comments (// lines before declarations)
• Backtick raw string handling for accurate brace counting

Rust Support

• Function declarations (pub, pub(crate), async, const, unsafe, extern "C")
• Struct (regular, tuple, unit), enum, and trait declarations
• impl blocks — methods extracted with parent_class set; trait impls tagged with impl:TraitName
• use statements (simple, grouped {A, B}, glob *, aliased, self)
• #[derive(...)], #[cfg(...)] attributes and /// doc comments
• macro_rules! definitions
• Raw string (r#"..."#) and nested block comment handling

Integration

• .go and .rs files included in default scan patterns
• target/ (Rust) and vendor/ (Go) added to default exclusions
• Import resolution for crate::/super::/self:: (Rust) and path-suffix matching (Go)
• 85 new tests, 293 total — zero regressions
