TOCropView.h declared `gridOverlayView` as a `TOCropOverlayView *` but only
forward-declared that class. Swift omits any property whose class it knows
solely as a forward declaration, so `cropView.gridOverlayView` did not exist
from Swift in any configuration -- framework, CocoaPods or bridging header.
That also put the `displayHorizontalGridLines` / `displayVerticalGridLines`
settings fixed in 3.2.0 out of reach for Swift callers.

Importing the header from TOCropView.h is the fix, but it only works if the
header is reachable under the framework's own module: TOCropOverlayView.h was
marked Project in both framework targets, so `<TOCropViewController/
TOCropOverlayView.h>` did not resolve and the Xcode 26 module verifier failed
on the quoted fallback. It is now Public in both targets, alongside the other
headers TOCropView.h already depends on, and imported with the same
conditional form used for TOCropViewConstants.h.

The test bundle's bridging header previously imported TOCropOverlayView.h
directly to work around this. That workaround is removed, which makes the
existing Swift test the regression guard: without the import in TOCropView.h,
CropViewControllerTests.swift no longer compiles.
