Various improvements (#614)

- Auto-select widgets in Launcher and apps with toolbars on devices without touch.
- Improved USB HID input reliability, cleanup
- Updated PSRAM settings to improve boot stability on supported devices.
- Prevented duplicate Wi-Fi event subscriptions during screen rebuilds.
- Updated docs
- Fixes in WifiManage and WifiConnect
- Reduced main task stack size
- Moved USB HID stack size to PSRAM when available
- app_manager_find_manifest() now returns a copy instead of a pointer

+# Building
+
+## Git
+
+The repository uses git submodules. Make sure to use `--recurse-submodules` on relevant git commands.
+
+## Simulator (Linux/macOS, no ESP-IDF needed)
+
+> [!IMPORTANT]
+> The simulator does **NOT** build or run on native Windows (Win32/PowerShell/cmd). This is
+> a hard platform limitation, not a missing tool or PATH issue — do not attempt `cmake -B
+> buildsim` on Windows, it will not work. WSL is a separate, Linux environment and is fine.
+
+```bash
+cmake -B buildsim -G Ninja
+ninja -C buildsim              # build firmware + tests
+./buildsim/Firmware/Tactility   # run simulator
+```
+
+## ESP32 firmware
+
+```bash
+python device.py <device-id>   # generate sdkconfig for device (e.g. lilygo-tdeck)
+python device.py <device-id> --dev  # dev mode: force 4MB partition table
+idf.py build                   # build firmware
+idf.py flash monitor            # flash and monitor
+```
+
+Device IDs are the folder names under `Devices/` (e.g. `lilygo-tdeck`, `m5stack-cores3`, `cyd-2432s028r`).
+
+### Windows: activating the ESP-IDF environment
+
+On native Windows, `idf.py` is not on PATH by default — it must be activated per-shell first.
+The install script places a PowerShell profile activator per IDF version at
+`%IDF_TOOLS_PATH%\Microsoft.v<version>.PowerShell_profile.ps1` (path controlled by the
+`IDF_TOOLS_PATH` environment variable, set to wherever ESP-IDF's tools were installed, e.g.
+`C:\Espressif\tools`). Source it before running any `idf.py` command:
+
+```powershell
+. "$env:IDF_TOOLS_PATH\Microsoft.v5.5.2.PowerShell_profile.ps1"   # match the installed IDF version
+Set-Location "<repo-root>"
+idf.py build 2>&1 | Select-Object -Last 250
+```
+
+This is Windows-specific setup (the main dev works on Linux, where `idf.py` is normally
+already on PATH via `export.sh`/`. ./export.sh` or a shell profile).
+
+## Devicetree
+
+A device implementation has a `.dts` file.
+The parser at `Buildscripts/DevicetreeCompiler/` converts DTS into C code.
+It's called from the `Firmware/` build process.
+
+## Tests
+
+Tests use Doctest and run on simulator (POSIX) target only:
+
+```bash
+cmake -B buildsim -G Ninja
+ninja -C buildsim build-tests
+cd buildsim && ctest --test-dir Tests
+```
