+- Reasoning token count now shown in session token summary for all users
+- Terminal bell no longer sounds on turn completion unless explicitly enabled via config
+- /resume picker no longer shows blank rows for sessions closed before sending a message

+- vote_memory tool calls are throttled per response and per interaction to prevent runaway voting bursts
