Jesty Thor Fix v1.7.0

Lower background watcher work, with the existing display and CPU Fix safeguards.

• Lower background watcher CPU work while retaining event-assisted transitions
  and safety polling. Research hardware A/B measured about 89% less daemon CPU
  in awake BOTH and TOP on AYN Thor firmware .377.
• Preserve display events around watcher waits and DRM snapshots.
• Keep completed CPU Fix startup proof intact during a guarded app update.
• No battery-life, gameplay or frame-time improvement is claimed.

The exact signed release APK passed guarded update, BOTH/TOP switching,
two dashboard-closed TOP power-button wake repairs with direct OFF_OK/RUNNING
results, and one normal supervised TOP reboot with confirmed CPU Fix proof.
The 10-minute awake TOP observation was on the experimental predecessor.
The existing early EGL startup limitation remains documented in the
validation report.

APK: Jesty-Thor-Fix-1.7.0.apk, version code 71, signed with the established key.
Install over the existing app to preserve settings; no uninstall is needed.
