DualSense touch movement currently has no position feedback in the preview, and the mic indicator only reflects a button press. This adds live touch and Windows microphone mute feedback, full RGB entry with opt-in lighting in native mode, and a single Windows title bar with working drag, maximize and restore controls.

Changes

• Carry both touch contacts through SDL input and snapshots, including motion without a touchpad click and independent release. Animate the focused detail preview with time-based smoothing and a short fading trail. Unfocused/reduced-motion previews use direct feedback; focus changes clear old trails. Touch dots and trails follow the configured LED colour, with an accent fallback for black/off.
• Display the actual mute state of the Windows default capture endpoint. An opt-in DualSense/Edge Mic-button action toggles that endpoint once per press; an explicit button assignment takes priority. COM discovery and mute operations run on a separate worker, without capturing audio.
• Expose the Light page in native mode behind a separate, default-off output switch. Add full #RRGGBB entry alongside swatches, and reflect the configured light in the controller drawing using the existing SDL LED output path.
• Integrate Windows window controls into the application header, use native caption hit testing for dragging, and explicitly restore maximized windows through the HWND. Preserve the existing non-Windows title-bar layout.
• Add English, Portuguese and Simplified Chinese strings, backward-compatible defaults, unit tests and touch-contact coverage in the Windows input loopback example.

Validation

• cargo fmt --all --check
• cargo clippy --workspace --all-targets --release --locked -- -D warnings
• cargo test --workspace --release --locked: 255 passed, 5 ignored.
• cargo build --workspace --release --locked
• python scripts/third_party_notices.py: generated notices unchanged.
• Windows SDL → ViGEm → XInput loopback, including touch motion without clicking, both contacts and independent releases.
• Manual verification on Windows 11 with a Bluetooth DualSense: touch feedback, actual microphone mute/unmute, physical RGB light changes, title-bar dragging, maximize and restore.

Behaviour notes

The mic target is the Windows default recording device, which can be the PC microphone over Bluetooth; this does not program the physical controller's mic LED. Native-mode lighting is opt-in because a game may also write the light bar. Touch smoothing changes presentation only, never game input.
