docs: Add performance audit report with optimization findings
PERFORMANCE_AUDIT.md documents a comprehensive code analysis identifying
12 optimization opportunities across the codebase:
High-impact findings (ICE score > 8):
1. Triple-EXISTS change detection -> LEFT JOIN (DONE)
2. N+1 label/assignee inserts during ingestion
3. Clone in embedding batch loop
4. Correlated GROUP_CONCAT in list queries
5. Multiple EXISTS per label filter (DONE)
Medium-impact findings (ICE 5-7):
6. String allocation in chunking
7. Multiple COUNT queries -> conditional aggregation (DONE)
8. Collect-then-concat in truncation (DONE)
9. Box<dyn ToSql> allocations in filters
10. Missing Vec::with_capacity hints (DONE)
11. FTS token collect-join pattern (DONE)
12. Transformer string clones
Report includes:
- Methodology section explaining code-analysis approach
- ICE (Impact x Confidence / Effort) scoring matrix
- Detailed SQL query transformations with isomorphism proofs
- Before/after code samples for each optimization
- Test verification notes
Status: 6 of 12 optimizations implemented in this session.
