feat(core): add T3W1 touch wakeup emulation support
- Enable USE_SUSPEND and USE_TOUCH_WAKEUP defines in T3W1 emulator
- Guard mouse events behind USE_TOUCH_WAKEUP in pm_suspend() SDL loop
- Respect touch_wakeup_get_enabled() state; ignore mouse clicks when
tap-to-wake is disabled so the emulator stays suspended correctly
[no changelog]
What changed, and why it matters
This commit adds emulator-only support for a new Trezor device (T3W1) to wake from a simulated low-power sleep state when the user taps the emulated touchscreen. It only affects the software emulator build, not real hardware, and does not change how secrets or user data are handled. There is no indication this is a security fix.
No security action required. Treat as normal feature commit for emulator support.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change enables USE_SUSPEND and USE_TOUCH_WAKEUP for the T3W1 emulator target, wires SDL mouse-button events into the Unix power_manager suspend loop, and honors the touch_wakeup_get_enabled() state so mouse clicks are ignored when tap-to-wake is disabled. It is a feature/enabling commit for emulator parity with a new hardware model. No cryptographic, storage, or trust-boundary logic is modified.
