Skate 3 Mobile v2.0.15

Skate 3 Mobile v2.0.15

Targeted native callback hotfix based on an AYN Thor crash report.

What the report proved

• Vulkan and the Qualcomm Adreno 740 System Driver initialized successfully.
• The guest address space, native renderer, High-End profile, pipelines, HDR,
  shadows, and FMV planes initialized before the crash.
• A grouped-operation worker called stale target 0xFFFDFFFF from guest return
  address 0x82B3CE2C.
• The generated retail function checks this optional callback as a boolean and
  follows its normal cleanup path when it returns false.

Fix

• Recover that exact return address by returning false from the optional
  content-validation callback.
• Keep all unknown indirect calls at other return addresses fatal so missing
  recompilation and memory corruption remain visible.
• Keep System Driver as the recommended default. This was not a Turnip or
  Vulkan initialization failure.

Verification

• Native ARM64 debug and release builds
• Android lint and APK assembly
• RG406V System Driver launch to the Skate 3 title screen at 60 FPS
• No new native crash during the RG406V launch path
• AYN Thor confirmation is still requested because this stale callback does not
  reproduce on the RG406V
