feat(backend): add LLM monitoring with step names, timing, and prompt logging
...
- LLMClient.complete() now accepts step_name parameter to identify processing step
- Logs prompt preview (first 100 + last 100 chars) at INFO level
- Logs processing time in milliseconds with token usage stats
- Updated QueryDecomposer, RelevanceFilter, and RAGService to pass step names

feat: Phase 1.3 query pipeline with decomposition, relevance filter, and response
...
- Add QueryDecomposer: extracts keywords from question via LLM JSON response
- Add RelevanceFilter: batch scores chunks 0-10, filters by threshold
- Add POST /api/v1/query endpoint with full 3-step pipeline:
1. QueryDecomposer.decompose() → keywords
2. RAGService.retrieve() → chunks from ChromaDB
3. RelevanceFilter.filter() → score and filter chunks
4. RAGService.generate_response() → bullet-point answer
- Fix SourceMetadata.upload_date type from datetime to str for flexibility
- Test-first: 13 new tests pass (5 decomposer, 5 relevance filter, 3 query endpoint)
- All Phase 1 tests: 41 passed, 2 skipped
