LGTM overall — implementation cleanly follows the existing pattern for boolean prop toggles (private field, equality short-circuit on Android, applyProps wiring on iOS, inclusion in applyUiSettings). Codegen + TS types + docs all consistent.

Two notes:

• Behavior change on iOS Google Maps. GMSMapView.settings.compassButton defaults to NO upstream; with compassEnabled defaulting to true, existing apps using the Google provider on iOS will start showing the compass button after upgrading. Likely intended (matches Apple/Android defaults), but worth calling out in the PR description / changelog.
• Web not updated. src/MapView.web.tsx doesn't handle the new prop. rotateEnabled has the same gap, so not a new regression — fine to defer.

Nit: PR body Summary / Test Plan are empty per the template in AGENTS.md.
