Shared forked agent — UI reads subconscious entries live

Browse source 
The forked agent is now behind Arc<tokio::sync::Mutex<Agent>>,
stored on SubconsciousAgent and passed to the spawned task. The
subconscious detail screen locks it via try_lock() to read entries
from the fork point — live during runs, persisted after completion.

Removes last_run_entries snapshot. Backend::Forked now holds the
shared Arc, all push operations go through the lock.
