"""Tests: profiles.list ``worker_session`` (freshest kanban/tool worker).

Why: kanban/tool worker sessions are deny-listed out of every conversation
list, so the desktop Bots roster showed a profile as idle ("3 hr ago")
while its kanban worker had been running for 12+ minutes
(NousResearch/hermes-agent#90268). profiles.list now reports the newest
DENIED row per profile as ``worker_session`` so roster UIs can light
ACTIVE NOW off the worker's ``last_activity_at`` heartbeat.

Contract under test:
- ``worker_session`` is the newest kanban/tool row: id, source, title,
  last_active.
- ``None`` when the profile has no worker sessions.
- ``last_session`` still never includes worker rows (existing deny intact).
- ``include_sessions: false`` skips the field entirely.
