v2.15.0

Bug Fixes

• Fix search returning 0 results (#79) — search_code_advanced with ugrep would return empty results due to a loop variable shadowing the search pattern, an invalid --ignore CLI flag, and errors being silently swallowed

Improvements

• Native .gitignore support for all search backends — ripgrep and ag now use built-in .gitignore handling instead of a custom reimplementation; ugrep uses --ignore-files; grep falls back to git grep in git repos
• Simplified search exclude architecture — removed the dual-filtering system (configure_excludes + _filter_results) in favor of letting each search tool handle exclusions natively, reducing ~280 lines of bug-prone code
• Config migration — additional_exclude_patterns moved from file_watcher config to project-level config (backward compatible — old configs auto-migrate)
• Rust specialized deep indexing — new strategy for Rust symbol extraction with safer resolution (PR #89)
• Hardened indexing — improved edge-case handling in indexing and request context
