docs: open a pull request when the task ends

[oxwen11]

Requirement

After a task ends, the agent opens a pull request instead of stopping.

Expected behavior

AGENTS.md tells the agent to open a pull request when the task ends. How to open it stays in the delivery stage.

Changes and risks

One sentence in AGENTS.md. No code or data change.

Verification

Docs only. The sentence is in the always-loaded AGENTS.md. Not runtime-verified.

Review and verification

• Head ae70ec61af44854c4a79bcc5ba65266beec5fd83, base 0920277492d381b108b520b341c449bcc3e3dbd8.
• Trusted rules: base 0920277492d381b108b520b341c449bcc3e3dbd8 (pull-requests.md unchanged on this PR).
• Required checks for this head: Check, react-doctor, and Publish @getpie/cli preview all succeeded. Check run.
• Review: the diff is one sentence in always-loaded AGENTS.md: "When the task ends, open a pull request." That is the requested finish rule. No code, data, trust boundary, or caller change. No blocking finding.
• Independent check: clean worktree pinned to ae70ec61, clean status. Only AGENTS.md differs from base. delivery.md is identical to base, so the trigger is not buried in the delivery stage. No product artifact is affected, so no Turbo build was run.
• CI-only exception not used: this is an agent instruction.
• Conclusion: pass. Another review is needed only if the head or the requirement changes.
