```
agent_ui: Use root thread helpers consistently (#54070)

Replace call sites that treated the active thread as the root thread
with the dedicated `root_thread_view` and `root_thread` helpers, and
simplify `ConversationView` lookups to avoid passing `cx` when it is
not needed.

Also emit token limit telemetry when usage crosses warning or exceeded
thresholds, while avoiding duplicate events for the same session state.
