fix(mpv): 恢复电视端自动电视直出，移除遗留全局暂停开关

Browse source

自动输出模式的电视直出被 506639c9b0 的临时 kill switch
(SURFACE_AUTO_STABILITY_GUARD_ENABLED=true) 永久否决：isAutoSurfaceDirectEnabled()
恒为 false，resolveSurfaceDirect() 的 OUTPUT_AUTO 分支也恒为 false，导致电视端自动档
只能走 GPU 合成 + 帧拷贝，4K 高帧率片源更容易掉帧与音频欠载。

22f2333317 已明确要求生产环境保留自动直出，且 P4-1(907bfca982)/P4-3(8250e2204f)
已加固 native Surface 关闭与终态拆除，该开关只剩副作用。

- 删除 SURFACE_AUTO_STABILITY_GUARD_ENABLED，保留按设备判定的零拷贝保护
  (ZERO_COPY_DEVICE_GUARD_ENABLED + MpvHardwarePolicy)；
- isAutoSurfaceDirectEnabled() 的唯一否决条件改为 isZeroCopyBlocked()；
- resolveSurfaceDirect() 的 OUTPUT_AUTO 分支恢复 leanback && autoEligible；
- 更新 MpvOutputModePolicyTest 期望值，并在 MpvStabilityGuardSourceTest 增加
  源码级回归断言，防止该全局开关被重新引入。

验证：MpvOutputModePolicyTest 9/9、MpvStabilityGuardSourceTest 6/6、
MpvOutputShutterSourceTest 4/4 全绿；变异测试证明新断言可失败；git diff --check 通过。
未做设备实测，待补项记录于 docs/MPV-AUTO-DIRECT-GUARD-RESTORE-20261017.md。

Verification: MpvOutputModePolicyTest 9/9 + MpvStabilityGuardSourceTest 6/6 + MpvOutputShutterSourceTest 4/4 全绿（BUILD SUCCESSFUL in 5m27s / 还原后 2m）；变异测试：重新引入 SURFACE_AUTO_STABILITY_GUARD_ENABLED 后 MpvStabilityGuardSourceTest failures=1（BUILD FAILED in 1m3s）并已从备份还原（grep -c=0）；git diff --check OK。未做设备实测，已在 docs 记录待补验证。
