This change refactors the GPU buffer packing logic in useGPUBuffers.ts to ensure that every cell position in the buffer is explicitly initialized with data, even if the source cell is null or empty. This prevents potential issues with uninitialized buffer data in the WebGPU rendering pipeline.


PR created automatically by Jules for task 5939271745233342426 started by @ford442

Refactored `packPatternMatrix` in `hooks/useGPUBuffers.ts` to ensure that both packed words for every pattern cell are unconditionally assigned. Previously, the second word was only written if the cell did not contain text or if it was explicitly parsed, potentially leaving uninitialized values in the buffer for certain edge cases (e.g. whitespace-only text).

Verified that `packPatternMatrixHighPrecision` already follows the correct pattern.
