This change implements an interface for running `@devcontainers/cli up`
and an API endpoint on the agent for triggering recreate for a running
devcontainer.
A couple of limitations:
1. Synchronous HTTP request, meaning the browser might choose to time it
out before it's done => no result/error (and devcontainer cli command
probably gets killed via ctx cancel).
2. Logs are only written to agent logs via slog, not as a "script" in
the UI.
Both 1 and 2 will be improved in future refactors.
