The API 29-36 `e2e` matrix uploaded only its test report, so an emulator
flake or a red leg (e.g. `E2E (31)` dying on a bare `sdkmanager` exit 1)
left nothing to diagnose. Bring the #334 API-37 diagnostics to the matrix,
inline (no changes to `e2e-preview`, which PR #372 is restructuring):
- Stream `adb logcat -v time` to `$RUNNER_TEMP/logcat-api<level>.txt` at the
top of both the "Run E2E tests" and retry reactivecircus steps (emulator is
booted there); backgrounded so gradle stays the exit-status-bearing command.
- New `if: failure()` step dumps device + runner state (adb devices, logcat
tail, emulator -accel-check, /dev/kvm, free -h, df -h) to the step log and a
diagnostics file; every probe guarded with `|| true`.
- New `if: always()` upload-artifact (same pinned v7 SHA) `e2e-diagnostics-api<level>`
carries the logcat + diagnostics files, `if-no-files-found: warn`.
- Make "Install SDK platform and build-tools" diagnosable: bounded 3x retry with
backoff for a transient sdkmanager failure, and print `--list_installed` on a
hard failure instead of a bare exit 1.
Keeps reactivecircus/android-emulator-runner and the existing boot-race retry.
Additive/diagnostic only; no boot-affecting flags change.
