Module watchdog 

Agent process watchdog: kills agent panes that exceed max-runtime or idle-output limits.

Runs every 60 seconds and inspects every running ShellController that has is_agent_pane = true. Two independent kill conditions:

A) term:agentmaxruntimehours — wall-clock runtime since spawn (0 = disabled) B) term:agentidletimeoutmins — minutes since last PTY byte (0 = disabled)

Both limits default to 0 (disabled) so the watchdog is opt-in.
