Fix stale existing exact-review publication revisions

[brokemac79]

Summary

Rebase an existing exact-review item above its target's durable publication head whenever a newer source event updates that item.

Problem

An existing review item can retain a local revision below the permanent publication head for the same target. A normal re-review then incremented only the stale local value (for example, 7 to 8 to 9 while the durable head was 12), so its artifact was rejected as superseded before publisher, state writer, router, or final comment delivery.

Implementation

• Compute the next existing-item revision as max(current + 1, publication head + 1).
• Keep the supersession audit's recorded next revision aligned with the rebased value.
• Add a lifecycle regression test for persisted revision 7, publication head 12, and a newer source event producing revision 13 that queues normally.

Validation

• pnpm run build:dashboard
• pnpm exec node --test --test-name-pattern "a later exact-review cycle still publishes after an earlier cycle raised the publication head|an existing exact-review item rebases above the publication head on a newer source event" test/dashboard-worker.test.ts
• pnpm exec oxfmt --check dashboard/exact-review-queue.ts test/dashboard-worker.test.ts
• git diff --check

Review closeout

• codex review --uncommitted: clean after focused proof.
• codex review --base origin/main: clean; reviewer also ran all 209 test/dashboard-worker.test.ts tests successfully.

Risk and rollout

This affects only an incoming newer source event updating an existing review item. It does not replay, mutate, or change already completed publications. It closes the pre-existing-item gap left after #836 seeded only new items above the durable head.

Related: #836, #849, and CSW-059 / openclaw/openclaw#111368.

I asked ClawSweeper to review this item again.
Action: item re-review queued (workflow sweep.yml, event repository_dispatch).
Result: when the review finishes, ClawSweeper will create the durable review comment if needed or update the existing comment in place.

Re-review progress:

• State: Waiting
• Detail: Another exact-head review is already active. The durable queue will retry after its lease expires.
