Key Hotspots (by severity):
Medium: Line-scanning loops in dev comment annotation + sync file I/O (dev-time only)
Medium: Unbounded header name cache (can leak memory in production)
Low: Unused build script comments (cosmetic)
Low: Oversized response pool (minor waste)
Low: JSON stringify/parse in session ops (acceptable; native Rust fallback for MemoryStore)
Recommendations:
Add LRU eviction to headerLookupNameCache
Debounce/batch file writes in dev comment writer
Add unused build script cleanup
Consider response pool shrinking strategy for long-running servers
