* feat: stand in for /dev/uinput so Steam Input's virtual pads reach games
* feat: present the pad to the Steam client as a Steam Deck controller over hidraw
* docs: log the uinput stand-in and the Steam Deck controller
* feat: feed the handheld's gyro and accelerometer to the Steam Deck controller
* feat: let the Steam page choose between the Steam Deck controller and the Xbox 360 pad
* feat: Deck back grips and trackpads on the second screen
* fix: serialize ring teardown with its writers, fall back to the Xbox pad when the Deck cannot be set up, and read motion only for a Deck
* fix: keep the second screen's choice through sleep and bring it back on wake
App name, app ID and code package: DroidDeck, com.droiddeck.launcher
(sources moved to com/droiddeck/launcher, the 68 JNI functions renamed
with them). The new app ID installs beside SteamDeck rather than over it.
Everywhere the name was the app's own: the sidebar title, the session
report, share zips, the shell title, wake-lock and log tags, User-Agents,
the Compose theme, the Download folder and switch files (droiddeck-env,
-osc, -driver, -tu-debug, -no-pad, -pad-log, -no-hud, -wlr-renderer; the
old names are not read), and inside the runtime (droiddeck-desktop,
Firefox's droiddeck.js, the shortcuts tag, the rumble socket, debug and
cache paths). Build scripts, CI artifact (droiddeck-apk), CMake project,
README and the progress log follow.
Kept on purpose: Valve's Steam Deck (the -steamdeck flag,
steamdeck_publicbeta/stable, 'Steam Deck mode', the steamos.cloud
package URLs) and names inside the hosted desktop package (steamdeck.png,
steamdeck-steam, steamdeck-bigpicture). 'Desktop installed' now tests for
labwc instead of the launcher the app stages itself. A committed
__pycache__ .pyc is removed.
