perf(deck): optimize card lookup by storing board_id/stack_id in metadata
Addresses reviewer feedback on PR #395 about O(n²) performance issue. Changes: - scanner.py: Add metadata field to DocumentTask with board_id/stack_id - scanner.py: Populate metadata during deck card scanning (both initial and incremental sync) - processor.py: Use metadata for O(1) card lookup via get_card() API when available - processor.py: Fallback to iteration for legacy data without metadata - context.py: Add _get_deck_metadata_from_qdrant() helper to retrieve metadata from Qdrant - context.py: Use metadata for fast path lookup in chunk context expansion - context.py: Add user_id parameter to _fetch_document_text() for metadata retrieval Performance Impact: - Before: O(boards × stacks × cards) iteration for each card lookup - After: O(1) direct API call using stored board_id/stack_id - Graceful degradation: Falls back to iteration for legacy data Testing: - All existing integration tests pass (test_deck_vector_search.py) - Type checking passes with no new errors 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
