Add daily-loop prepare and readiness checks

Make the local chat-host loop explicit and cheap so users can warm the machine once instead of rediscovering environment and guest setup on every session.

Add cache-backed daily-loop manifests plus the new `pyro prepare` flow, extend `pyro doctor --environment` with warm/cold/stale readiness reporting, and add `make smoke-daily-loop` to prove the warmed repro-fix reset path end to end.

Also fix `python -m pyro_mcp.cli` to invoke `main()` so the new smoke and `dist-check` actually exercise the CLI module, and update the docs/roadmap to present `doctor -> prepare -> connect host -> reset` as the recommended daily path.

Validation: `uv lock`, `UV_OFFLINE=1 UV_CACHE_DIR=.uv-cache make check`, `UV_OFFLINE=1 UV_CACHE_DIR=.uv-cache make dist-check`, and `UV_OFFLINE=1 UV_CACHE_DIR=.uv-cache make smoke-daily-loop`.
