## Summary & Motivation
- Manifest coverage now declares an entry for every matrix app, uses real Vitest skips instead of silent early returns, and fails when a targeted app's manifest is missing, unknown, or unparseable.
- Retries are scoped to deployment e2e runs (`DEPLOYMENT_URL` set), so a flaky unit or integration test can no longer be hidden by a second attempt.
- The stop-workflow cookbook parks on a sleep between iterations, giving the hook an observable barrier to race instead of a fixed delay, and the AbortController hook test waits on queue state rather than a 10ms timer.
- The world-postgres direct-storage fixture drives its run to a terminal state so the conformance worker doesn't recover and replay an unregistered workflow.
- Generated e2e result sidecars are ignored and the committed copies removed; they're CI artifacts, not fixtures.
## Test Plan
Existing coverage runs in CI. With retries disabled: the cookbook agent suite passed 8/8, the two stop-workflow tests passed 10/10, and the AbortController hook replay test passed 25/25 under `CI=1`. The manifest suite skips 52 apps explicitly when nothing is built, and fails on unknown or missing targeted apps. The Docker-backed Postgres spec could not run locally (Testcontainers found no container runtime); `@workflow/world-postgres` typechecks.
