ci(ui-e2e-gate): wire the warmup-eviction runner leg — ratchet red on develop again (#11698 landed script-only)

[lalalune]

Found during #11628 verification — third strike in the same race. Follow-up to #11646 and #11702.

Problem

The packages/scripts/__tests__/ui-e2e-runner-coverage.test.ts ratchet is red on develop again: #11698 (warm-up eviction fix, merged 2026-07-02 ~23:5xZ) added packages/ui/src/components/shell/__e2e__/run-warmup-eviction-e2e.mjs with a test:warmup-eviction-e2e package script but without any workflow leg:

packages/ui/src/components/shell/__e2e__/run-warmup-eviction-e2e.mjs: script "test:warmup-eviction-e2e" is not invoked by any .github/workflows/*.yml — wire a leg (ui-fixture-e2e.yml) or delete the runner with justification

Change (7 insertions, 1 file)

.github/workflows/ui-e2e-gate.yml: add a "Warm-up message eviction e2e" leg next to its shell-family siblings (after fused-wake), and add output-warmup-eviction to the artifact upload paths. The package script already exists on develop — no package.json change needed.

Verification (local, this branch = develop + this commit)

Check	Result
bun test packages/scripts/__tests__/ui-e2e-runner-coverage.test.ts	1 pass / 0 fail (red on develop without this)
bun run --cwd packages/ui test:warmup-eviction-e2e (exact CI invocation)	exit 0, PASS, 8/8 ✓ assertions (optimistic bubble survives reconcile, retryable failed turn, exactly-once delivery on Retry, no page errors)
actionlint .github/workflows/ui-e2e-gate.yml	clean

Regenerated output-warmup-eviction/ evidence from the local run was restored to HEAD; the checked-in evidence from #11698 remains canonical.

Rebased #11704 onto current develop 62002b1c755 and revalidated.

Local verification:

• bun test packages/scripts/__tests__/ui-e2e-runner-coverage.test.ts -> 1 pass / 0 fail / 2 assertions
• actionlint .github/workflows/ui-e2e-gate.yml -> clean
• git diff --check origin/develop...HEAD and git diff --check -> clean
• bun run --cwd packages/ui test:warmup-eviction-e2e -> PASS, 8/8 assertions:
  • optimistic user bubble renders on send
  • user bubble survives the warm-up 503 + reconcile reload
  • retryable failed assistant turn appears
  • failed turn explains message did not reach the agent
  • retry delivers exactly once
  • agent reply lands after retry
  • failed turn is reconciled away after persistence
  • no page errors

I opened the generated final screenshot (03-delivered-after-retry.png) and confirmed the user message remains and the retried agent reply is present. Regenerated output files were restored so this PR remains the intended one-file workflow change.

Validation after rebase onto origin/develop (62002b1c755):

• Confirmed .github/workflows/ui-e2e-gate.yml invokes the existing packages/ui script test:warmup-eviction-e2e.
• Confirmed artifact upload includes packages/ui/src/components/shell/__e2e__/output-warmup-eviction.
• Ran the fixture and manually reviewed generated screenshots/logs: warm-up screen, retryable failed turn with surviving user bubble, and successful retry/reconciled final reply. The local run regenerated tracked output files, and I restored those side effects so the branch remains workflow-only.

Checks run:

• bun test packages/scripts/__tests__/ui-e2e-runner-coverage.test.ts
• actionlint .github/workflows/ui-e2e-gate.yml
• git diff --check origin/develop...HEAD && git diff --check
• bun run --cwd packages/ui test:warmup-eviction-e2e

No approval from me because this PR is self-authored by lalalune.
