feat: add loop, schedule, and chat CLI commands (#149)

* Add metrics collection and terminal performance tests

* feat: add loop, schedule, and chat commands with slash-namespaced RPC

Introduce three new server-side features with CLI command groups:

- `paseo loop` — iterative agent execution with verify-check/verify-prompt
- `paseo schedule` — recurring tasks on interval or cron cadence
- `paseo chat` — chat rooms for agent-to-agent coordination

All features use new slash-namespaced RPC methods (e.g. `loop/run`,
`schedule/create`, `chat/post`) instead of flat message types, backed
by file-based persistence and wired through the existing WebSocket
session dispatch.

* test: stabilize loop schedule chat rollout
