ActiveTools wrapper: replace SharedActiveTools Arc<Mutex<Vec>>

Browse source 
New ActiveTools struct with proper methods: push, remove, abort_all,
take_finished, take_foreground, iter, len. Lives directly on AgentState,
no separate Arc<Mutex> needed.

TUI reads active tools through agent.state.try_lock(). Turn loop uses
helpers instead of manual index iteration.
