[Test][Android] Add Sandbox compatibility acceptance gate

[Huxpro]

Summary

• add durable Playground-host instrumentation gates for Android compatibility features in [Feature][Android] Add fixed Lynx viewport support #120-[BugFix][Android] Reject unsafe Lynx viewport threading #127
• cover fixed viewport, shared density, default thread strategy, typed template fetching, unsafe viewport/thread rejection, full-page orientation policy, and failed-view retry behavior
• add a checked-in real Lynx bundle and a one-command SG1/Sandbox runner
• dynamically lease and release devices; no serial is hard-coded

Matrix

• compatibility: 3 tests
  • real bundle via page typed template fetcher
  • fixed 320x480 Lynx viewport
  • shared density 3.25 across two independent Lynx views via public LynxContext.screenMetrics
  • default PART_ON_LAYOUT strategy
  • fixed viewport + MULTI_THREADS rejected before view or Activity creation
  • all safe page thread strategies (ALL_ON_UI, MOST_ON_TASM, PART_ON_LAYOUT, MULTI_THREADS without a fixed viewport) render a real bundle
  • pre-load listener runs with the bridge ready and before template fetch
  • global per-page fetcher factory is invoked
• retry: 1 end-to-end test
  • FAIL -> FAIL -> SUCCESS
  • fresh retry token and stale-token rejection
  • release invalidation
  • legacy non-retry error view
• orientation: 6 isolated tests
  • typed landscape and portrait
  • explicit SYSTEM over global landscape
  • canonical screen_orientation
  • unset Android system behavior
  • embedded view does not mutate host orientation

Reproduce on SG1

ANDROID_HOME=/data00/home/xuan.huang/android-sdk \
  scripts/android-device-acceptance.sh

The script builds both APKs, leases a fresh Lynx Sandbox device, installs, runs all 10 tests in isolated app processes, captures screenshots/logs/hashes, releases the lease, and creates a tarball. It requires an exact clean checkout and fails closed unless the release response confirms the leased serial.
