fix(agent_loop): harden loop against redundant agents, bad merges, wrong closures
- Add merge verification to the pending_issue PR path (section 2), matching the catch-up scan fix: if the PR is still open after _merge_pr returns, set State/Question instead of claiming success and leaving the issue closed with an unmerged PR. - Replace _latest_ci_run() with _latest_main_ci_run() that filters to non-pull_request events on the 'main' prettyref. The old limit=1 query could return a PR-branch run, causing section 3 to misread CI as failed and spawn a ci-fix agent when main was actually fine. - Guard against redundant ci-fix agents: when the same main CI run ID has been failing since the previous ci-fix started (agent pushed to a branch, not main), check for any in-flight CI run before spawning another agent. - Issue agent prompt: explicitly forbid "Closes #N" / "Fixes #N" in commit messages. The loop is responsible for closing issues after CI passes; commit-keyword auto-close would race with or bypass that logic. - Global ci-fix prompt: restore "push directly to main" (ci-fix agents need to land on main to clear the main CI run) and keep the "no issue references" guard added in the previous commit.
