Merge ready

Drive the current work to the point where the only remaining step is Ben's own review and merge. The deliverable is a pushed branch with a clean pnpm ci:check, checkpoint commits along the way, and an open PR with a high-level description plus review instructions.

Never merge the PR. Ben always reviews last.

0. Figure out the starting point

This skill composes with feature work — it is not only a review pass:

• Invoked alongside a build request ("build X, make it merge-ready"): implement the feature/fix first, committing as you go, then continue below. The review phases cover all changes on the branch vs origin/main, not just the last edit.
• Invoked on existing work ("make this branch merge-ready"): start directly at step 1. The scope is git diff origin/main...HEAD plus anything uncommitted.

1. Sync with main

• git fetch origin main. If the branch is behind, merge origin/main in and resolve conflicts (favor main's version for code this branch didn't intentionally change).
• Checkpoint: commit the merge before starting review, so conflict resolution is auditable separately from review fixes.

2. Multi-axis subagent review
