fix: cleanup suspended Clawdbot CLI processes

Add cleanupSuspendedCliProcesses() to kill accumulated suspended processes
from isolated sessions that don't share sessionIds (e.g., cron jobs).

- Only targets Clawdbot processes (--session-id pattern)
- Only kills suspended processes (state T)
- Only triggers when >10 processes accumulated
- Does not affect user's Claude Code sessions
