MAESTRO: Add electron-rebuild verification for better-sqlite3 on all platforms

- Added 14 new tests in stats-db.test.ts verifying:
  - package.json: postinstall script, dependencies, asarUnpack config
  - CI/CD workflow: platform builds, architecture verification, --force flag
  - Native module structure: binding.gyp and .node binary existence
  - Platform-specific paths and database import verification

- Updated release.yml with better-sqlite3 architecture verification:
  - Added verification step after initial postinstall (Linux ARM64)
  - Added verification in Linux x64 package step after electron-rebuild
  - Added verification in Linux ARM64 package step after electron-rebuild
  - Added verification in unpacked app.asar contents (Linux ARM64)

All 225 tests in stats-db.test.ts pass.
