fix: gracefully degrade when sqlite-vec cannot load#61
Merged
Conversation
sqlite-vec requires dynamic extension loading in SQLite, which is not available in all Bun builds (notably some macOS versions). Previously this crashed the entire CLI with 'does not support dynamic extension loading'. Now: - SidecarDatabase.tryLoadVec() catches the error and sets hasVectorSearch=false - SearchIndex skips vector KNN queries, falling back to FTS5-only search - CompactionEngine skips vector-based duplicate merging - bootstrapSidecar() prints a warning when vector search is disabled - All other functionality (FTS5 search, task graph, audit, etc.) works normally
