PR Babysitter

Objective

Babysit a PR persistently until one of these terminal outcomes:

• PR is merged or closed.
• CI succeeded, no unaddressed review comments, not blocked on review approval, and mergeable.
• A situation requires user help (infra issues, exhausted flaky retries, permissions, or ambiguity).

Do not stop merely because a single snapshot returns idle while checks are still pending.

Inputs

• No PR argument: infer from the current branch (--pr auto)
• PR number or PR URL
