Prevent chaos create-pull-request fallback when branch already exists

[Copilot]

Safe-output PR creation in the chaos bundle fuzzer was intermittently falling back to issue creation when reruns hit an existing remote branch name. The failure path was triggered by preserve-branch-name: true without allowing ref recreation.

• Root cause

  • create-pull-request attempted to push a branch that already existed remotely.
  • With branch-name preservation enabled, push was rejected and safe-output downgraded to fallback issue behavior.

• Workflow configuration change

  • Updated safe-outputs.create-pull-request in chaos-pr-bundle-fuzzer.md to allow replacing existing remote refs:
    • Added recreate-ref: true
  • Kept preserve-branch-name: true intact to preserve deterministic branch naming for chaos scenarios.

• Generated workflow sync

  • Recompiled chaos-pr-bundle-fuzzer.lock.yml so runtime workflow behavior matches source workflow config.

safe-outputs:
  create-pull-request:
    title-prefix: "[chaos-test] "
    preserve-branch-name: true
    recreate-ref: true

Pull request overview

Updates the chaos bundle fuzzer workflow to prevent create-pull-request safe-output from falling back (e.g., to issue creation) when reruns hit an already-existing remote branch name, by enabling ref recreation on collisions.

Changes:

• Enable recreate-ref: true alongside preserve-branch-name: true for safe-outputs.create-pull-request in chaos-pr-bundle-fuzzer.md.
• Regenerate chaos-pr-bundle-fuzzer.lock.yml so the compiled workflow’s safe-outputs handler config includes recreate_ref: true.
