Issue Slice Autopilot

Drive a complex issue to completion across multiple PRs with minimal or no user intervention.

This skill is for long-running tasks where one giant PR is too risky. It repeatedly:

1. selects the largest sane slice with no overlap with in-flight work,
2. implements and validates the slice,
3. runs $commit-and-push,
4. runs $enter-merge-queue until merged,
5. refreshes state and repeats.

Core Rules

• Keep exactly one active PR at a time.
• Always avoid overlap with open PRs touching the same area.
• Prefer the largest independent slice that has clear done criteria.
• Do not leave a slice half-shipped; either finish it or skip it for now.
• After each merged PR, re-evaluate the issue from current main.
