Claude c2aef4cbc7 fix: keep Hermes session across runs and speak long replies as a digest (2.5.3)
Over the runs transport Hermes never reports the session it attached to a
run in the SSE stream, only in GET /v1/runs/{id}. EveFlow only read it in the
polling fallback, so the locally generated id was sent again and again and
each message opened a fresh Hermes session, losing the conversation context.
The client now adopts the run's session id after every run.

Long answers are now spoken as a digest: the first sentences (configurable,
4 by default) plus the closing question, followed by a short notice that the
full text is on screen. The default instructions ask Hermes to open long
replies with the essentials and to rely on the ongoing conversation.
