Story Crater Bot bcb4e30ec2 feat: M3.8.2 cache aligner integration — metrics + headers (3 tests) ...

CacheMetrics struct (40 LOC):
- stable_prefix_bytes, dynamic_tail_bytes
- drift_metric (0.0-1.0 ratio)
- cache_eligible flag (drift < 0.3)
- compression_ratio() and header_* methods

PromptBuilder::cache_metrics() (40 LOC):
- Calculates cache alignment metrics for query+chunk pairs
- Integrates CacheAligner output
- Gets compression ratio from ContextOptimizer
- Used for HTTP headers and observability

HTTP headers ready for client integration:
- X-Cache-Stable-Bytes
- X-Cache-Drift
- X-Cache-Eligible
- X-Compression-Ratio

3 new tests:
- test_cache_metrics_stable_query
- test_cache_metrics_compression_ratio
- test_cache_metrics_header_drift

Total: 117 mem-core tests (114 before + 3 new)
