Finish Task

End-of-task lifecycle: gates → review → commit. Counterpart to new-task (which starts the branch). Commit/PR naming is owned by git-conventions.

This skill owns the gate sequence and policy, never the commands — those are stack-specific and get discovered from the project.

Gate sequence

Run in this order; stop on first red and enter the fix-loop:

1. Tests
2. Typecheck
3. Lint
4. Static analysis
5. Format (apply, then re-stage)
