FLUTTER WEB HOT RELOAD BROKEN FOR EXTERNAL ENTRYPOINTS

Flutter's web-server hot restart silently fails when your entrypoint lives outside lib/, leaving developers debugging phantom code changes that never shipped.

The web hot reload pipeline has a URI format mismatch in `toMultiRootPath` [1] that breaks hot restart entirely for integration tests or any entrypoint outside the standard lib/ directory. This is a hard stop for teams running integration_test/main.dart workflows - the app shows stale code after every change until you full reload. In parallel, Flutter shipped a fix for iOS display link documentation [2] that clarifies the VSync lifecycle for platform engineers, and iOS signing now displays team IDs inline [3], saving developers a trip to Apple's portal mid-build. On the Kotlin front, the team is restructuring test federation to isolate stdlib changes [6] and bumped Gradle to 9.5.1 [7], both foundational moves for build reliability. Swift's compiler tightened availability scopes [4] and rewired closure lifetime dependencies [5] to eliminate wasteful convert_function instructions after partial_apply, a subtle win for performance-sensitive code.

→ Review iOS signing output in next build to confirm team ID display flutter/flutter [plan]
