Make PR Description Updater use triggering PR context for update_pull_request

[Copilot]

The PR Description Updater workflow reported structured incompletion because its single allowed update_pull_request call was consumed during recovery from argument/target mismatch, before final content submission. The workflow config required explicit PR targeting while the prompt instructed identifier-less calls.

• Root cause

  • safe-outputs.update-pull-request was configured with target: '*', which requires pull_request_number.
  • Prompt guidance directed the agent to avoid passing PR identifiers, creating a conflicting contract and retry path that exhausted max: 1.

• Change made

  • Removed wildcard targeting from .github/workflows/pr-description-caveman.md so update_pull_request resolves to the triggering PR context.
  • Recompiled the workflow, updating .github/workflows/pr-description-caveman.lock.yml to reflect the new safe-outputs contract.

• Behavioral impact

  • update_pull_request no longer requires explicit pull_request_number in this workflow.
  • The final synthesized description can be submitted in the single allowed call, avoiding quota loss to corrective retries.

safe-outputs:
  update-pull-request:
    body: true
    title: false
    operation: replace
    max: 1
