The short version

What changed, and why it matters

This commit simply increases three internal version counters for the Trezor T3W1 hardware wallet from 1 to 2 (or 0 to 1). These counters are used to prevent downgrading to older, potentially less secure firmware, bootloader, or security monitor software. The change itself does not fix a bug or add a feature; it is a routine housekeeping step to keep downgrade protection working after a release. There is no direct security vulnerability shown in the diff.

Recommended action

No immediate action required. Treat as routine release housekeeping. If tracking the T3W1 release cycle, ensure the corresponding signed images and release notes reflect the new monotonic versions and that downgrade protection still behaves as expected.
