ready-for-pr

Run the same quality gates CI runs — types, lint, dead code, tests — and fix what fails until the branch would pass. Then mark the current branch's GitHub PR ready for review if it is still a draft. Use only when the user explicitly says "ready for PR", "run the checks", "is this ready to ship", or "will CI pass". A bare implementation, commit, submit, PR update, or PR opening request does not run this suite.
