deps: bump react-native to a 0.88 nightly and drop the Windows patch

React Native 57706 ("Fix build-from-source on Windows: use JVM temp dir
instead of hardcoded /tmp", 908872a6, 2026-07-28) landed on main after
the 0.87 branch cut, so it ships on the 0.88 line and not in 0.87.0-rc.4.
Verified in the published artifact, not just the tree: the tarball for
0.88.0-nightly-20260809-db662caea carries the fix in settings.gradle.kts,
the exact file (and path) we were patching. Our patch is now redundant.

Dropping it is what makes Android build. Patching a dependency makes pnpm
encode the patch hash into the virtual store directory as
`..._patch_hash=<hash>`, and prefab — which the Android Gradle plugin runs
over react-native's package directory — parses a positional path
containing `=` as an option name and dies with "Error: no such option".
That is google/prefab#187, open since March and
hitting every pnpm user with a patched dependency. With no patched
dependencies there is no `=` in the store, so the bug goes untriggered.

Requires react-native-test-app >= 5.4.8, which widened its peer range to
`0.76 - 0.87 || >=0.88.0-0 <0.88.0` — a prerelease window covering exactly
these nightlies. 5.4.5 did not accept 0.88 at all, so the floor moves up.

Everything the AGP 9 work depends on is unchanged on this line: AGP 9.2.1,
Kotlin 2.2.0, and react-native-test-app still resolves Gradle 9.4.1 for
0.88, matching the pinned wrapper.
