Subject: [PATCH] fix: dynamically resolve RCTRootContentView for Expo SDK 56
 static-framework builds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Looking up `RCTRootContentView` via `NSClassFromString` instead of
referencing the type statically. The static reference produced an
`Undefined symbols ... _OBJC_CLASS_$_RCTRootContentView` link error
under React Native 0.82 / Expo SDK 56 builds that use static
frameworks. Mirrors the approach taken in 7936d90 for
`FollyConvert.h`.

Widens the return type of `closestParentReactContentView` from
`RCTRootContentView?` to `RCTView?` — required because referencing
`RCTRootContentView` in a type annotation reintroduces the same
static link.

Fixes #40
