Why

A new Spark app created from main fails to build its macOS dev build on Xcode 26.2 (Swift 6.2.3):

react-native-nitro-image/macos/MacImage.swift:55:16: error: type of expression is ambiguous without a type annotation
    return try render(abs(bounds.width), abs(bounds.height)) { context in

macos/MacImage.swift is not upstream code: Spark's patches/camera/react-native-nitro-image.patch creates it. In rotate(), the multi-statement closure passed to render() mixes CGFloat (the rotated CGRect bounds) and Double (the image size), and Swift 6.2's type checker gives up on inferring it. The Kitchen Sink does not link NitroImage, so its builds did not catch it.

What

• Convert the rotated bounds to Double and capture the source size before the closure.
• Annotate the closure parameter as CGContext.
• Update the hunk header (+1,183 to +1,185).

Same rotation math, only explicit types.

Verification

• The diff package (which native-patches.cjs uses to apply patches) applies the updated patch to an empty file, and the output matches the hand-fixed file byte for byte.
• spark build --dev --platform macos of a fresh spark create --universal app (packed from main) fails without the fix and builds with it, on Xcode 26.2.

Not verified: an older Xcode such as CI's macos-latest. The change only adds explicit types, so it should still compile there, and CI covers it.
