v1.6.0-paxx12-22 Extended Firmware released

Hey everyone! Just released v1.6.0-paxx12-22 of the extended firmware for the Snapmaker U1.

What's new:

• Base firmware bumped to Snapmaker's stock 1.6.0 (new nozzle/filament options, AI monitoring issue reports, faster loading/unloading, several stock bug fixes)
• DragonBreath — community open chamber-heater firmware is now a selectable option alongside Panda Breath, and is the recommended choice going forward. If you're on Panda Breath already, there's a one-click "Migrate to DragonBreath" action that flashes it over Wi-Fi, no USB or internet needed
• Bypass MCU (Disconnected) mode — you can now keep printing on the other three toolheads when one toolhead's board is dead or its cable is unplugged entirely, not just when its thermistor fails
• Fixes: SET_SPOOL_ID E-prefixed lane fallback, filament manager websocket auth gap, Moonraker mDNS not resolving after boot, SpoolLink same-UID channel resolution, and five PRs that got silently reverted by the 1.6.0 firmware bump got restored
• Fluidd and Mainsail bumped to their latest versions

Full changelog: https://github.com/paxx12-snapmaker-u1/SnapmakerU1-Extended-Firmware/pull/663

Heads up: Panda Breath support is planned for removal in a future release, so if you're still on stock Panda Breath firmware, consider migrating to DragonBreath when convenient — it's a one-click action once you're on this release.

Big thanks to @plastikman (https://github.com/plastikman) for building and maintaining DragonBreath.

The release is currently marked as the pre-release if no bugs will be observed, it will become release in one week time.

Happy printing! Feel free to ask questions or report issues on GitHub.
