fix: prevent agents from running indefinitely after app quit

Agents kept running after closing AgentCompany because worker processes
auto-recreated on exit, retry timers were never cleared, child CLI
processes weren't terminated, and orchestration had no quit guards.

Changes:
- Add isQuitting guards to all orchestration/automation entry points
- Track and clear all setTimeout/setInterval timers on quit
- Send cancel-run to all active CLI processes before killing worker
- Add destroyed flag to prevent worker recreation after intentional destroy
- Add quit confirmation dialog: Stop All & Quit / Minimize to Background / Cancel
- Bump version to 0.4.96
