test: mock KeyvSqlite and KeyvNedbStore to prevent SQLITE_CANTOPEN error

Added mocks for @keyv/sqlite and keyv-nedb-store to use in-memory Map
instead of file-based storage. This prevents SQLITE_CANTOPEN errors
during tests when the lib module tries to create SQLite cache files.

The gh-priority-sync task imports from @/lib which uses KeyvSqlite for
Notion caching and KeyvNedbStore for GitHub caching. These need to be
mocked to avoid file system access during tests.
