ci: drop the harness-android job until the suite actually runs

It failed on every push in ~3s with an AbortError, so the repo showed a
permanently red X for a gap that is already known and documented.

Two stacked problems block it, neither a quick fix:
- react-native-harness 1.4.1's runtime needs EventTarget, which RN 0.83
  on Hermes does not provide and the harness does not polyfill
- Harness serves an Expo manifest at / that the prebuilt app never
  requests, so its entry bundle is never evaluated

The suite, its config and 'yarn harness:android' all stay; only the CI
job goes, with a comment explaining when to restore it.

+  # execute yet — Harness serves an Expo manifest the prebuilt app never asks
+  # for, so its runtime globals are missing. Running it here would mean a
+  # permanently red job for a known, documented gap; see the "Harness: wired,
+  # not yet green" section of the README. Run it locally with
+  # `yarn harness:android`. Re-add this job once the entry point is resolved.
