Crash in RewindOCRService.extractTextWithBounds — array index out of bounds

[omi-discord-vector]

Bug: Omi macOS app crashes 1-2 minutes after launch when Rewind screen capture is active.

Version: Omi Beta 11.5, macOS 26.3

Crash details:

• Thread 9 crashes with EXC_BREAKPOINT (SIGTRAP) — _assertionFailure in libswiftCore
• Root cause: array index out of bounds in __SwiftNativeNSArrayWithContiguousStorage._objectAt()
• Call stack: RewindOCRService.extractTextWithBounds(from:) → RewindIndexer.processFrame() → Apple Vision TextRecognition framework
• The OCR result array is accessed at an invalid index, likely a race condition or empty result set not handled

Stack trace (key frames):
