Summary

• Add ordered, additive before/after hooks for all 17 standard and semantic lifecycle boundaries, preserving provider-specific contexts and existing validation/result callbacks.
• Run both preparation hook sets inside trusted Git staging. Capture the precise failing stage, timing, and registration index without changing the original exception.
• Keep the existing commit, build, tag, publication, and recovery implementations unchanged; the existing checkpoint task remains, and publication retains its established preparation behavior.
• Document the complete stage catalog, exact Actions/standalone ordering, skipped/reused stages, retries, callbacks, and safety constraints. Include a consumer example using built-in KeepAChangelog and the standard workflow without private overrides or custom publication orchestration.

Validation

• Full bundle exec rake spec phase: 313 examples passed, including installed-gem consumer processes; line coverage was 99.21%.
• bundle exec rake rubocop: 131 files, no offenses; bundle exec rake build and git diff --check passed.
• Real-Git integration verifies preparation hook edits enter the release and next-development commits and confirms publication retains its existing rebuild behavior.

No YAML interface changes, live publication, or release dispatch.
