When AQ_FLEET_PR=1 and a claimed fleet job carries a `repo`, run the agent in an
isolated checkout on branch aq/job/<fleetJobId> (off baseBranch), then on a passing
verify commit/push and `gh pr create`. The PR URL + branch are recorded in the meta
and reported on lease release (-> the coordinator stores them on the run).
- fleet-client: parse repo/baseBranch from the claim, carry them in frontmatter;
fleet_report_insights now sends prUrl/branch.
- _fleet_pr_prepare (clone/fetch + branch, local-path aware, identity fallback) and
_fleet_pr_open (commit/push/gh pr create). WIP checkpointing is skipped for PR jobs
(the pushed branch is the durable artifact).
- New flags: AQ_FLEET_PR, AQ_FLEET_REPOS_DIR, GH_BIN. README documented.
- selftest: +1 case (bare-repo origin + gh stub) — branch pushed, PR opened, prUrl
reported on release. Full self-test PASS.
