…colbymchenry#1532) Official Node.js binaries do not compile FTS5 by default, causing codegraph init to fail with 'no such module: fts5'. Added runtime FTS5 detection: - Split schema execution to try FTS5 separately, skip on failure with warning - Added fts5Available flag to DatabaseConnection and QueryBuilder - Bulk-load and search paths skip FTS5 operations when unavailable - Search falls back to LIKE + fuzzy matching when FTS5 is missing

What Problem This Solves
codegraph v1.5.0 uses Node.js built-in
node:sqliteand requires FTS5, but official Node.js binaries do not compile FTS5 by default. This causescodegraph initandcodegraph indexto fail on any standard Node.js installation withError: no such module: fts5.Why This Change Was Made
The schema at
src/db/schema.sql:117creates an FTS5 virtual table unconditionally. When FTS5 is not available in the SQLite build bundled with Node.js, the entire schema execution fails, preventing codegraph from functioning at all.User Impact
codegraph now works on Node.js builds without FTS5. When FTS5 is unavailable:
