This is number 2 of 5 pull requests in an effort to add agent script
ordering. It adds a drpc API that is exposed via a local socket. This
API serves access to a lightweight DAG based dependency manager that was
inspired by systemd.
In follow-up PRs:
* This unit manager will be plumbed into the workspace agent struct.
* CLI commands will use this agentsocket api to express dependencies
between coder scripts
I used an LLM to produce some of these changes, but I have conducted
thorough self review and consider this contribution to be ready for an
external reviewer.
