fix: implement deletion grace period and vector sync status tool

This commit addresses issues with vector database synchronization that
were causing test failures:

1. **Deletion Grace Period** (scanner.py)
   - Fixed premature deletion of documents due to pagination cursor
     inconsistencies in Notes API
   - Implemented 2-scan verification with 1.5x scan interval grace period
     (15 seconds default)
   - Documents must be missing for 2 consecutive scans before deletion
   - Documents that reappear are removed from deletion tracking
   - Prevents false deletions during concurrent note creation/indexing

2. **Vector Sync Status Tool** (server/notes.py, models/notes.py)
   - Added nc_notes_get_vector_sync_status MCP tool
   - Returns indexed_count, pending_count, status, and enabled fields
   - Enables tests and clients to wait for vector sync completion
   - Uses lifespan context to access document queue and Qdrant client

3. **Test Improvements** (test_sampling.py, conftest.py)
   - Added temporary_note_factory fixture for creating multiple test notes
   - Updated all sampling tests to wait for vector sync completion
   - Adjusted score_threshold to 0.0 for SimpleEmbeddingProvider
     (feature hashing produces low-quality embeddings)
   - Fixed CallToolResult extraction (removed ["result"] key access)
   - Removed invalid @pytest.mark.asyncio markers (anyio mode)

All integration tests now pass successfully.
