Babysit My PRs

Authenticate gh, derive the current user and origin repository, then discover all open PRs authored by that user. Never touch another author's branch.

For each PR, collect CI state, required-job presence, base divergence, merge state, inline review threads, top-level reviews, and PR comments. Classify it as:

• Work needed: a mechanical base merge, settled CI fix, or concrete review correction.
• Deferred: a semantic conflict, optional suggestion, integration-host failure, scope/security/design judgment, or ambiguous feedback.
• Clean: no actionable feedback, required checks present and green, and no conflict.
