Added

• missing_dispose — flags disposable controllers/notifiers (AnimationController, TextEditingController, ScrollController, TabController, PageController, FocusNode, ValueNotifier, and more) that are never disposed in State.dispose().
• uncancelled_subscription — flags StreamSubscription fields that are never cancelled.
• uncancelled_timer — flags Timer fields that are never cancelled.
• One-click quick-fix for every rule: injects the correct release call (dispose() / cancel()) into dispose(), creating the method if absent.
• Example project wired with expect_lint assertions that double as the integration test.
