Feat: Create NAPI types module with all type definitions

- Create crates/codegraph-napi/src/types.rs with all NAPI type definitions
- Move existing types from lib.rs to types.rs (transaction, version, branch types)
- Add new search types: SearchResult, SearchOptions, DualModeSearchResult
- Add new configuration types: CloudConfig, EmbeddingStats
- Update lib.rs to import and re-export types from types module
- All types include #[napi(object)] macro for TypeScript bindings
- SearchOptions includes #[derive(Default)] for convenience
