Part of #77.

Today's action_run_job data shows build and e2e each take about 4.7 min. e2e waited for build (needs: build) even though the suite builds from source and never uses the images, so every PR's gate was a chain of about 10 min.

e2e has no needs now, so it starts immediately on PRs and on main.
promote has needs: [build, e2e]. It's the only step that uses the published :<sha>, so the guarantee that the image exists before it's retagged is kept where it matters.
On main this also brings :stable forward by about 5 min.

The cost: a PR whose build fails (on lint, for example) still spends a runner slot on e2e. Check names are unchanged, so the protection rule is unaffected.

This PR's own run should show e2e starting at the same time as build.

Part of #77. Today's `action_run_job` data shows `build` and `e2e` each take about 4.7 min. `e2e` waited for `build` (`needs: build`) even though the suite builds from source and never uses the images, so every PR's gate was a chain of about 10 min. - `e2e` has no `needs` now, so it starts immediately on PRs and on `main`. - `promote` has `needs: [build, e2e]`.

e2e waited on build for images it never uses — the suite builds from
source — so every pull request's gate was a ~10 minute chain of two ~4.7
minute jobs (measured from action_run_job on 23 September). e2e now starts
at once; promote, the only step that needs the published :<sha>, needs both
jobs. On main that brings promote forward by the same five minutes.

The cost is a runner slot spent on e2e when build fails, e.g. on lint.
Check names are unchanged, so branch protection is unaffected.
