Greptile Summary

This PR adds a "Performance & Reliability" section to the v1.81.14 release notes, highlighting latency improvements (up to 13% lower p99 latency) from 20+ micro-optimizations. It also adds an entry for PR #21213 (streaming connection pool fix) to the connection management changelog section.

• Adds performance benchmark data (mean, p50, p99 latency reductions) with a supporting image
• Documents the streaming connection pool fix and Redis connection pool reliability improvements with mermaid diagrams
• Adds missing changelog entry for PR fix: close streaming connections to prevent connection pool exhaustion #21213 under "Connection management & reliability"
• All links (benchmarks page, PR references) and image references are valid

Confidence Score: 5/5

• This PR is safe to merge — it only adds documentation content to release notes with no code changes.
• This is a pure documentation change adding a performance section to release notes. No code is modified, no logic changes, no risk of runtime impact. The markdown content is well-structured, links are valid, and the image file exists.
• No files require special attention.
