+  - Offers to create feature branch automatically instead of committing directly
+  - Configurable via `GIT_PROTECTED_BRANCHES` environment variable
+  - Resolves issue where commits to protected branches would fail on push
+
+### Changed
+- **doc-guardian:** Hook completely rewritten to be truly non-blocking
+  - Removed all analysis logic that could trigger workflow stoppage
+  - Now outputs only minimal notification for config file changes
