K-Snake button remapping missing from panel despite protocol support (mouse-protocol#68 merged)

[yanhenrique-dev]

Problem

K-Snake X11 button remapping was merged upstream in OpenMouse-Project/mouse-protocol#68 (5 commits, merged into main by @snekxs on 2026-09-07), but the official panel still shows no button-remap card for K-Snake.

Root causes

1. Panel has no ksnake traits. src/device/traits.ts BY_FAMILY has no ksnake entry, so advancedSection resolves to false and src/app/cards/availability.ts hides the ButtonMappingCard — even though the driver now publishes buttonMappings/buttonOptions. The protocol half landed; the panel half did not.
2. Tab filter drops the card. filterTabs in src/app/App.tsx does not account for has.buttonMapping, so the card is filtered out even when data is present.
3. Deployment lag. The app consumes the driver via git URL (@openmouse/protocol in package.json), which npm snapshots at install time — the merge only reaches the official site after a reinstall + redeploy.

Fix in flight

• feat(cards): polling header readout, button tab gating, fixed rows #206 (open polling-header-and-button-cards branch) adds the ksnake traits entry, the filterTabs fix, and the fixedButtons guard (keeps Left Click locked like the vendor panel).
• Follow-up driver bits (showAdvancedSection, fixedButtons in MouseStatus) are still local and will come as a separate mouse-protocol PR.

Expected

After #206 merges and the site redeploys with a fresh install, K-Snake shows the button-remap card with Left locked.
