- Add helper methods to locate match lines and find containing symbols
- Modify search_fts, search_fts_exact, search_fts_fuzzy to return complete
code blocks (functions/methods/classes) instead of short snippets
- Join with files table to get full content and file_id
- Query symbols table to find the smallest symbol containing the match
- Fall back to context lines when no symbol contains the match
- Add return_full_content and context_lines parameters for flexibility
- Include start_line, end_line, symbol_name, symbol_kind in SearchResult
This improves search result quality by returning semantically meaningful
code blocks rather than arbitrary 20-byte snippets.
