fix(team): clean single traveling pulse + delegations start at the architect

- The pulse is now one dash with an effectively infinite gap, animated
  origin→target→off with fill:forwards — no wrap-around second bar and no
  snap-back to origin when it arrives (fixes the ghost bar). Slower, ease-in-out
  so it eases out of the origin card and into the target's last branch.
- Real delegation/review pulses now originate at the ARCHITECT (the root's
  single child), not the CEO above it — so a task assigned to an agent no longer
  visibly starts from the CEO. Cuts a 3-edge cascade to 2 for a PO-level agent.
