The green pulse now visualises real task flow instead of looping randomly:
- delegation (task → in_progress/reassigned) fires a green pulse architect→agent
and the agent card turns 'active' (green ring + badge);
- review submission (→ review) fires an amber pulse agent→architect and the
card enters the 'reviewing' state.
Pulses are one-shot, created per transition (SSE-driven, deduped against a
baseline snapshot) and removed on arrival, which lights the destination node.
At rest only the connectors breathe faintly. Active state recoloured green to
match the pulse. Verified: delegation→down+active, review→up+reviewing.
