Profile integration:
- CameraDevice.get_save_config() serialises camera_index, simulate,
  resolution, fps — cameras now persist in .labdaq profiles
- ProfileManager.register/unregister_device_factory() lets plugins
  register their device classes for profile restoration without
  core → plugin dependency
- MotionCapturePlugin registers CameraDevice factory on load/unload

Camera configuration:
- Add Frame Rate combo to CameraPanel (Default/15/24/30/60/120 fps)
  defaults to 30 fps; flows through to CAP_PROP_FPS on connect
- tracker.start() accepts fps param alongside existing resolution

Tracking persistence:
- CameraTracker.is_running() — checks thread alive state
- MotionCaptureWindow initialises _connected from tracker.is_running()
  so reopening the window resumes the live feed without restarting
  the camera or losing the active tracking state

Window state:
- Plugin saves px_per_mm + camera_idx when window closes
- Reopened window restores saved values and syncs mode/shape UI
  from tracker state via restore_ui_state() (signals blocked to
  avoid resetting tracker)
- Window type changed to Qt.WindowType.Window for independent
  close button on all Linux WMs

<title>Upgrade motion capture: template matching, frame-freeze selection, resolution</title>

Tracking:
- Add "template" mode (default) using snapshot + shape-masked matchTemplate
- Add "csrt" mode as alternative for texture-rich targets
- set_roi_rect(x, y, w, h, frame_rgb) initialises from exact selection rect
- set_roi() delegates to set_roi_rect (centred square, backwards-compat)
- start() accepts resolution=(w, h) to set camera capture resolution

Selection UX:
- Replace QLabel feed with FrameSelector widget (custom QWidget)
- "Click to Track" freezes frame; user scrolls to zoom (anchored to cursor),
  right-drags to pan, left-drags to draw rubber-band selection
- Shape preview: rectangle or inscribed ellipse depending on mode
- "Confirm Selection" extracts template from frozen frame and starts tracking
- "Clear" cancels selection or clears active tracking

Configuration:
- CameraPanel adds Resolution combo (Default / 640×480 / 720p / 1080p / 1440p)
- CameraDevice stores and forwards resolution to tracker.start()
- Template Match listed first in Mode combo; shape combo hidden for CSRT

Replace camera index spinbox with a combo listing detected cameras by
name. On Linux enumerates /dev/video* and reads device names from sysfs
(fast, no probing). Fallback probes cv2.VideoCapture indices 0-7 on
other platforms. Simulation entry always appended as last option.

Also adds explicit simulation mode (index -1) to tracker.start() and a
rescan button (⟳) in both the main window and the Settings &gt; Plugins
widget.

<title>Added Motion Capture plugin</title>

Tracks a user-selected point via webcam (OpenCV CSRT tracker) and
streams x_pos / y_pos pixel coordinates as live channels into the
acquisition pipeline. Falls back to a Lissajous figure simulation
when opencv-python is not installed, so the plugin works immediately
without hardware.

- tracker.py: background thread, real camera + sim modes, thread-safe API
- device.py: BaseDevice reading x/y from tracker, wires into engine
- filter.py: custom pixel_to_mm filter (registered in FILTER_CLASSES)
- window.py: floating tool window, live feed, click-to-track ROI selection
- plugin.py: LabPlugin wiring all pieces together, toolbar button,
  settings widget, profile save/restore

Also: PluginAction.button_ref_callback lets plugins store a ref to their
toolbar button so they can uncheck it when their window closes.

opencv-python install note added to requirements.txt.
