Always emit persist-credentials: false with actions/checkout

[Copilot]

Prevents GITHUB_TOKEN from persisting in git config after checkout by always emitting persist-credentials: false in all generated actions/checkout steps.

Changes

• Updated 4 checkout generation sites:

  • compiler_yaml.go: Main job checkout
  • push_to_pull_request_branch.go: buildCheckoutRepository() helper
  • copilot_participant_steps.go: Participant checkout
  • create_agent_task.go: Agent task checkout

• Added test coverage: checkout_persist_credentials_test.go validates persist-credentials is emitted across all checkout scenarios

• Recompiled workflows: All 65 .lock.yml files updated with the security parameter

Example

Generated checkout steps now include:

- name: Checkout repository
  uses: actions/checkout@08c6903cd8c0fde910a37f88322edcfb5dd907a8
  with:
    persist-credentials: false

Original prompt

Always emit persist-credentials: false with actions/checkout

uses: actions/checkout@v4
with:
  persist-credentials: false

[Copilot]

The addition of an empty require () block appears unnecessary and unrelated to the PR's purpose of adding persist-credentials: false. This change adds no functional value and should be removed to keep the PR focused on its security objective.
