feat: make E2E targeted workflow wait for dispatched run result

Problem#

The dispatch-e2e job fired-and-forgot after dispatching to agent-core-e2e, making the PR check cosmetic — it always went green regardless of whether E2E tests actually passed.

Task / Link#

Closes #499

Changes#

• Added statuses: write permission to the workflow
• Added timeout-minutes: 30 to the dispatch-e2e job
• Record dispatch timestamp and capture the dispatched run ID via retry loop (up to 60s)
• Poll the run to completion with gh run watch --exit-status — job now fails if E2E fails
• Post a commit status to the PR head SHA with the E2E conclusion and a direct link to the run

Notes#

• Run identification filters by --created ">=$DISPATCH_TIME" to avoid picking up a concurrent dispatch's run; the 5s×12 retry loop handles the typical 5–15s delay between dispatch and run creation
• Post commit status step uses if: always() so the status is reported even on failure or cancellation

Testing#

• Verified workflow YAML is syntactically valid
• Logic verified by code review against plan acceptance criteria
