ship-issue-ghlisted

Drive a GitHub issue (or ordered list of issues, or parent issue with a managed `## Sub-issues` task-list) from `pending` to `merged` through the implement → open-PR → address-review → merge loop. GitHub-only. Stateless across sessions — GitHub Issues + the PR's check runs are the sources of truth. **Usage:** `/ship-issue-gh <arg>` — the skill self-arms its own `/loop`. Invoke once and walk away. Where `<arg>` is one of: - A single issue: `<owner>/<repo>#<n>` (or `#<n>` when invoked inside the target repo's git working copy) - A comma-separated ordered list (each entry must be fully qualified — no `#<n>` shorthand in a list, since the list can span repos): `<owner>/<repo>#<65>,<owner>/<repo>#<66>` - A **parent issue** with a managed `## Sub-issues` task-list — children are resolved from the task-list and walked in body order - A **milestone**: `milestone:<owner>/<repo>/<num-or-name>` — expands to the milestone's non-terminal issues, ordered by `createdAt` ascending Any shape may carry a trailing `--no-compact` flag to suppress the compact-on-merge prompt — see [`../_shared/compact-on-merge.md`](../_shared/compact-on-merge.md). > The architecture (state machine, blocked-user triggers, escape hatches, locked decisions) lives in `DESIGN.md` alongside this file. The label scheme + marker comments + task-list fence live in `../scaffold-sub-issues-gh/github-conventions.md`. Read both before changing behavior. This file is the operational procedure. --- ## Phase 0: Parse inpu
