agent: switch from tokio::sync::Mutex to std::sync::Mutex

Browse source 
The agent lock is never held across await points — turns lock briefly,
do work, drop, then do async API calls. std::sync::Mutex works and
can be locked from sync contexts (screen tick inside terminal.draw).

Fixes: blocking_lock() panic when called inside tokio runtime.
