Ship

Closes the loop from a finished branch to an open PR.

The shape of the workflow you're completing:

/to-prd       → PRD issue
/to-issues    → slice issues (children of the PRD)
afk-cook      → AFK slices ship, issues close
/tdd          → HITL slices ship, commits include `Closes #N`
ship          → review gate + PR + PRD-close ref

When ship runs, slice issues are already closed (afk-cook closes them on SLICE_COMPLETE; /tdd commits should include Closes #N). The parent PRD is still open. ship's job is to open a PR whose Closes #<PRD> ref will close the parent PRD when the PR merges.
