v0.5.184

What's new

• orchestra linear add --spawn now nests the new workspace under the calling agent.
  It previously hardcoded detached: true, so a ticket spawned by an agent always
  landed top-level in the sidebar with no way to override it — even from a promoted
  orchestrator, where nesting is the entire point. The caller's workspace id was
  already being sent and used to inherit the repo, then discarded before the spawn.
  It's now threaded through, matching orchestra spawn's behaviour.

  The Tickets sidebar's "spawn from ticket" button is deliberately unchanged and
  still creates a top-level workspace: a user clicked it, so there is no calling
  agent to nest under.
