📝 Walkthrough

Walkthrough

The PR refactors pruneMessages to use index-based slicing and updates GitHub release parsing to accept variable-length commit SHAs. Release parsing now uses a single-pass loop, with tests for 8-character and 40-character hashes.

Changes

Maintenance updates

Layer / File(s)	Summary
Index-based message pruning src/utils/chat-logic.ts, .jules/engine.md	pruneMessages replaces repeated shift() calls with a start index and slice(start). Existing message-count, content-length, and trailing-assistant rules remain unchanged.
Release hash and body parsing src/utils/github-releases.ts, src/__tests__/github-releases.test.ts	Release parsing accepts 7- to 40-character hexadecimal SHAs. splitReleaseBody processes lines in one pass. Tests cover 8-character and full 40-character hashes.
