feat(regionSelector): Crop implies Rect - auto-swap Freehand on entry

Entering Crop while Freehand is active swaps selection to Rect; the R
key and the Rect/Freehand tabs are inert while Crop is on. Leaving Crop
keeps Rect (no restore); already-Rect swaps are no-ops.

-- **Crop Mode** - Press `C` (or the new Instant/Crop toolbar tabs) to switch the region selector into Crop mode: releasing a selection opens an adjustable editor (8 resize handles + interior move, min-size and screen clamping, live size label) instead of capturing immediately; **Enter**/**Space** or the confirm button captures, **Escape** returns to drawing. Works with both selection modes (a circle loop seeds the editor with its bounding box). Works for screenshots and recording alike; configurable via `regionSelector.crop.minSize`/`handleSize`

 - **`R` Hotkey** - Toggles Rect/Freehand selection mode inside the overlay (the "Circle" tab is now labeled **Freehand**; config keys keep their `circle` names)
 - **Freehand True-Shape Capture** - Freehand selections now capture only the pixels inside the drawn loop (transparent outside, via an ImageMagick polygon mask). OCR flattens onto white; recording and the crop editor remain rectangular (true-shape applies to Instant-mode freehand only)
 - **`regionSelector.dragThreshold` Config Key** - Pixel dead-zone (default `6`) for the region selector's click/drag discriminator; `0` disables it, restoring the previous per-pixel sensitivity (circle mode always uses `0` — every circle gesture is the drawn shape)

 ### Freehand Selection
 
-Freehand captures the true drawn shape: the output is cropped to the loop's bounding box and everything outside the loop is transparent. OCR flattens the mask onto white (tesseract dislikes alpha); recording always captures the bounding rectangle (wf-recorder is rectangle-only). In Crop mode the mask is discarded — the crop editor is a rectangle tool, so a freehand seed adjusted there captures the adjusted rect.
