Fix push_target remote reuse and non-fatal per-repo errors

- git_mirror: reuse existing push_target remote via remote_set_url
  instead of failing on 'remote already exists' on subsequent cycles
- mirror_cycle: catch per-repo errors instead of propagating with ?
  so one failed clone doesn't abort the remaining 87 repos
- Add PLAN.md with bug tracking checklist
