Security
- Removed the optional context-compression MCP shell-execution surface so commands remain subject to normal host approval and sandbox controls.
- Hardened repository-memory change-impact analysis against Git argument injection and outside-root writes.
- Added regression coverage for side effects, malicious revisions, malformed input, and valid revision ranges.
Users of Citadel v1.4.1 should upgrade to v1.4.2.
