Add 4-hour chaos PR bundle fuzzer workflow for safe-output create-pull-request stress testing

[Copilot]

New Feature

Introduces a new agentic workflow that runs every 4 hours to stress-test safe-output create-pull-request git patch/bundle packaging using randomized persona-driven scenarios.
The workflow is constrained for safety and signal: max 5 PRs/run, 4h expiry, test-in-progress labeling, chaos/ branch naming requirement, and small scoped edits only.

• ### What does this feature do?

  • Adds .github/workflows/chaos-pr-bundle-fuzzer.md (and compiled .lock.yml) for scheduled + manual execution.
  • Instructs the agent to generate randomized personas and scenario strategies, execute small git change flows, and create PRs through safe outputs.
  • Persists run strategy history in cache-memory to bias toward under-tested patterns with fuzzy/random selection across runs.

• ### Why is this feature needed?

  • Exercises the robustness of gh-aw safe-output PR patch/bundle generation under varied, realistic git operation patterns.
  • Provides bounded chaos coverage without broad repository risk or large-change noise.

• ### Implementation details

  • on: schedule: "every 4 hours" with workflow_dispatch.
  • safe-outputs.create-pull-request guardrails:
    • max: 5
    • expires: 4h
    • labels: [test-in-progress]
    • allowed-files: ["tmp/chaos/**", "scratchpad/chaos/**"]
    • excluded-files: [".github/workflows/**"]
    • protected-files: blocked
    • preserve-branch-name: true (to preserve chaos/ prefix emitted by scenarios)
  • Prompt-level hard requirements enforce:
    • branch prefix chaos/
    • exact plain-text PR test notice
    • small edits only (1–3 tiny edits/PR)

safe-outputs:
  create-pull-request:
    max: 5
    expires: 4h
    labels: [test-in-progress]
    preserve-branch-name: true
    allowed-files:
      - "tmp/chaos/**"
      - "scratchpad/chaos/**"
    excluded-files:
      - ".github/workflows/**"
    protected-files: blocked

Pull request overview

Adds a new agentic workflow that runs every 4 hours to stress-test the safe-output create-pull-request git patch/bundle handling using randomized persona-driven small-change scenarios, with strict guardrails (max 5 PRs, 4h expiry, chaos/ branch prefix, narrow allowed-files scope, protected-files blocked).

Changes:

• New workflow source .github/workflows/chaos-pr-bundle-fuzzer.md defining safe-outputs config, hard requirements prompt, persona/strategy randomization guidance, and cache-memory ledger usage.
• Auto-generated compiled .github/workflows/chaos-pr-bundle-fuzzer.lock.yml containing the full GitHub Actions workflow (activation, agent, detection, safe_outputs, update_cache_memory, conclusion jobs).
