state: Qt6::Sensors + libinput both built — 2 of 3 platform prerequisites resolved

Platform prerequisite status:
- Qt6::Sensors: BUILT (v6.11.0, 520KB pkgar, dummy backend)
- libinput: BUILT (v1.30.2, with libevdev v1.13.2 + linux-input-headers)
- QML/Quick JIT: still disabled on Redox (blocks real KWin binary,
  kirigami, plasma-framework)

KWin: now attempts real cmake build with Sensors + libinput deps
enabled. Falls back to redbear-compositor shim on cmake failure
(QML/Quick gate). Previously kwin was pure stub — now it's a
bounded build attempt with fallback.

Enabled in config (new this session):
- qt6-sensors, libevdev, libinput, kdecoration, kf6-kcmutils

Previously OOTB dependencies now resolved:
- libevdev → libinput → KWin real build path opened
- linux-input-headers → libevdev → libinput chain
- qt6-sensors → KWin Sensors dependency satisfied
