refactor(daemon): upgrade Drizzle v1.0-beta + migrate better-sqlite3 → node:sqlite

- Upgrade drizzle-orm from 0.43.1 to 1.0.0-beta.23
- Replace better-sqlite3 with node:sqlite (DatabaseSync) in:
  - sense-runtime.ts (Drizzle driver)
  - log-store.ts (raw SQL)
  - all test files
- Replace sqlite.pragma() with sqlite.exec('PRAGMA ...')
- Replace sqlite.transaction() with manual BEGIN/COMMIT/ROLLBACK
- Update CLI init command to verify node:sqlite instead of better-sqlite3
- Remove better-sqlite3 and @types/better-sqlite3 from dependencies
- Zero native addons remaining in the monorepo 🎉

Closes #67
