Plan collab

A plan is a markdown Artifact edited live by a person in the browser and by your local seat: the archdev plan collab start process, which joins the Artifact channel as an agent actor and relays signals to you. The plan lives only in the Artifact; nothing is written to disk. You never touch the channel directly. You drive the seat with short-lived commands that find it through a handle file.

browser  <--OT ops + signals-->  Artifact channel  <-->  seat (archdev plan collab start)
                                                              ^  loopback + handle file
                                              you: signals / read / suggest / complete / apply / run

archdev plan collab --help and each verb's --help list the commands; the CLI is the authority when it disagrees with this file. Every verb prints one JSON object per line. Everything needs a signed-in user session.
