Bug Fixes

Bulk protocol (87AD:70DB GrandVision): Fixed frame header format — was missing magic bytes, command type, image dimensions, and mode byte. Device received data but couldn't parse it.
Bulk USB open: Fixed Resource busy error — kernel driver detach now runs before set_configuration() instead of after.
Bulk frame writes: Pixel data sent in 16 KiB chunks (was single bulk write). ZLP frame delimiter always sent.
Bulk cleanup: Properly claims and releases USB interface.
Legacy autostart: Glob for trcc*.desktop files instead of hardcoding names.
