Open a Desk

Create a new desk in the workshop with the standard structure.

When to use

• The operator wants to start a new workstream
• Work arrives that doesn't belong to any existing desk
• A topic needs its own frame (its own history, its own priors)

What it creates

Given a workshop directory and a desk name, create:

desks/<desk-name>/
  journal.md       # persistent memory — read at start, written at end
  .signals/        # structured signal output (JSON) — dashboard reads this
