Use USB descriptors and MTP identity instead of the static libmtp product label. Monitor attachment, discard stale UI responses, clear disconnected views, and release slow MTP sessions in the background while preserving operation serialization.
Publish 0.1.1 with immutable source history. Cover discovery, names, unplugging and slow disconnect with native and UI regressions. Verify real Pura 70 Ultra identity and prompt disconnect; run the newest published backend during Git-source checks.
