Two DualSense (UHID) fixes surfaced live on the Bazzite host:
- Battery: serialize_state never set the input report's status byte (struct off 52 →
r[53]), so hid-playstation read battery capacity 0 and SteamOS warned "low battery"
even on a fully-charged pad. Set it to 0x0A (discharging, low nibble 0xA → 100 %) —
a virtual pad has no real cell. (Forwarding the client pad's real charge is a later
feature.) Regression assert added to the layout test.
- Rumble diagnostic: log the silent→active transition when forwarding a buzz on the
0xCA plane, so a live test can tell "host never receives rumble from the game"
(Steam Input / parse) apart from "client doesn't render it". Once per buzz, no spam.
