feat(multitask): kontext-getaggte Activity + kontext-scoped Cancel (Restpunkte 1+2)

Beide Restpunkte teilen eine Verkabelung: die projectId fliesst jetzt bis zum
Proxy und zurueck in die agent_activity-Events.

Restpunkt 1 — per-Kontext Activity-Indikator:
- Brain: proxy_client.chat_full(project_id) → payload.aria_project_id;
  agent.py gibt active_project_id mit.
- Proxy routes.js: liest aria_project_id, taggt Tool-/Stream-Hooks damit,
  trackt Subprozesse pro Kontext.
- Bridge: _emit_activity(project_id) + payload.projectId; /internal/agent-activity
  reicht projectId durch; send_to_core/_process_core_response taggen thinking/idle
  mit dem Turn-Kontext.
- App: agentActivityByCtx-Map; „ARIA denkt"-Indikator zeigt nur den
  fokussierten Kontext statt global zu flackern.

Restpunkt 2 — kontext-scoped Cancel (Barge-In):
- Proxy: neuer /cancel {projectId} killt NUR die Subprozesse eines Kontexts
  (_cancelByProject); /cancel-all bleibt fuers NOT-AUS.
- Bridge: soft cancel_request → _cancel_proxy_for_project(projectId) statt des
  toten Diagnostic /api/cancel. Hard bleibt /cancel-all.
- App: cancel_request + Abbrechen-Button tragen die fokussierte projectId.

Damit laufen Kontexte in der App echt parallel: Arbeit in Projekt A wird durch
Senden/Abbrechen in Hauptchat oder Projekt B nicht mehr abgewuergt, und der
Indikator gehoert zum sichtbaren Chat.
