Convert F2-F5 screens to ScreenView trait with tick() method.
Each screen owns its view state (scroll, selection, expanded).
State persists across screen switches.
- ThalamusScreen: owns sampling_selected, scroll
- ConsciousScreen: owns scroll, selected, expanded
- SubconsciousScreen: owns selected, log_view, scroll
- UnconsciousScreen: owns scroll
Removed from App: Screen enum, debug_scroll, debug_selected,
debug_expanded, agent_selected, agent_log_view, sampling_selected,
set_screen(), per-screen key handling, draw dispatch.
App now only draws the interact (F1) screen. Overlay screens are
drawn by the event loop via ScreenView::tick. F-key routing and
screen instantiation to be wired in event_loop next.
InteractScreen (state-driven, reading from agent entries) is the
next step — will eliminate the input display race condition.

The agent lock was held for the entire duration of turn() — including
API streaming and tool dispatch awaits. This blocked the UI thread
whenever it needed the lock (render tick, compaction check, etc.),
causing 20+ second freezes.
Fix: turn() takes Arc<Mutex<Agent>> and manages locking internally.
Lock is held briefly for prepare/process phases, released during all
I/O (streaming, tool awaits, sleep retries). Also:
- check_compaction: spawns task instead of awaiting on event loop
- start_memory_scoring: already spawned, no change needed
- dispatch_tool_call_unlocked: drops lock before tool handle await
- Subconscious screen: renders all agents from state dynamically
(no more hardcoded SUBCONSCIOUS_AGENTS list)
- Memory scoring shows n/m progress in snapshots
