Mirror the e2e-preview job's proven wedge-capture onto the API 29-36 matrix
legs, now that #454 replaced reactivecircus/android-emulator-runner with the
same hand-provisioned manual boot e2e-preview uses.
Each leg now wraps its `./gradlew connectedDebugAndroidTest` in the #404
`timeout -k 30s $WEDGE_TIMEOUT` wrapper; on a hang (exit 124) capture_wedge
dumps the smoking gun (running test via TestRunner logcat, SIGQUIT thread
dumps of the app + instrumentation processes, service list / service check,
dumpsys activity+window, logcat tail) into a per-API-level
wedge-diagnostics-api<level> artifact (if-no-files-found: ignore so healthy
runs stay quiet).
Why it cannot re-hang the legs (the #406/90dfb18 revert reason): the wrapper
wraps ONLY the foreground gradle client, never the backgrounded emulator --
identical in shape to e2e-preview's run_shard. The reverted #404 wrapper wrapped
reactivecircus's emulator boot; #454 removed that. WEDGE_TIMEOUT reuses preview's
1200s: healthy matrix legs run ~8.3-12.0 min (whole job), well under 20 min, which
is itself well under this job's 50-min cap, so a genuine wedge is caught + captured
and a false trip on a healthy run is not possible.
