docs(rules): reflect native builds moved to the pre-push gate

Update the pre-push gate table: Android (assembleDebug assembleRelease) and iOS (simulator,
no-signing) builds now run locally on push, scoped to native/gradle/pods/deps changes. Note the
CI android-build was removed (hung 3+ hours). Verified: assembleRelease builds both APKs locally.

+**The native builds are a LOCAL pre-push gate, NOT in CI.** The hosted `android-build` CI job hung for
+3+ hours on the native C++ builds and was removed; both builds now run on push (scoped above so JS-only

 **Requirements:**
 - SwiftLint: `brew install swiftlint` (skipped with a warning if not installed)
-- Android checks require the Gradle wrapper in `android/`
+- Android checks require the Gradle wrapper in `android/`; the iOS build needs a booted-or-available

 **Workflow implication (TDD / adversarial red-first):** write a failing test, commit it red (commit is
 free), then drive it green; the branch must be green before `git push` (the gate blocks a red push).
