Action required

1. Review the release notes for changes that may affect agnix validation rules.
2. Update crates/agnix-core/src/config.rs (ToolVersions / SpecRevisions) if the new version changes a validated field.
3. Update knowledge-base/RESEARCH-TRACKING.md "Last Reviewed" for Gemini CLI.
4. After triage, run the workflow with update_baselines: true (and optionally tool: gemini-cli) and copy the JSON snippet from the job summary into .github/tool-release-baselines.json.
