* fix(app): refine compact composer controls and native scrolling
Consolidate responsive agent controls and model browsing inside the compact sheet. Preserve manual native scrolling by suspending sticky bottom maintenance while the user owns the viewport.
* fix(app): suppress recoverable resume refresh errors
Resume revalidation can race host reconnection and reject while the host is offline. Treat the refresh as deferred so development LogBox does not surface a recoverable disconnect.
* fix(app): stabilize compact model sheet loading
Let the model list consume the sheet space above persistent controls as the sheet expands. Keep unresolved defaults in a loading state so Select model only represents a genuinely empty selection.
* fix(app): preserve route anchors during native scroll
* fix(app): preserve native scroll intent and sheet dismissal
* fix(app): keep compact sheet styles composable
The inverted list's native position maintenance fought the sticky-bottom controller as the live message grew. Let the controller exclusively own the Android sticky-bottom anchor while preserving position maintenance when reading history.
* feat(app): refine tool call summaries and scrolling
Keep summary groups stable from the first tool call, preserve live activity feedback, and scroll expanded groups to the latest entry. Consolidate web scrollbar styling around the native browser mechanism.
* refactor(app): reuse tool call height constant
* fix(app): preserve tool call summary state
* fix(app): refresh web tool groups on expand
* fix(app): preserve grouped tool errors
