Race condition where `shutdown()` ran before initialization completed\n\nConceived by Romuald Członkowski - www.aiadvisors.pl/en\n\nCo-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>\n\n* test: add unit tests for shared-database module\n\nAdd comprehensive unit tests covering:\n- getSharedDatabase: initialization, reuse, different path error, concurrent requests\n- releaseSharedDatabase: refCount decrement, double-release guard\n- closeSharedDatabase: state clearing, error handling, re-initialization\n- Helper functions: isSharedDatabaseInitialized, getSharedDatabaseRefCount\n\n21 tests covering the singleton database connection pattern used to prevent\n~900MB memory leaks per session.\n\nConceived by Romuald Członkowski - www.aiadvisors.pl/en\n\nCo-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>\n\n---------\n\nCo-authored-by: Claude Opus 4.5 <noreply@anthropic.com>",
