the cut-off notice is its own event now rather than an error: nothing is broken
and nothing is lost but the turn, so the row says what happened and offers the
one action that fixes it. the conversation is already durable — the claude
session id is written through to disk and passed back as resume: — so retry
just resends the prompt on a session the fresh agent picks up with full
context. read back out of the transcript, so a second window on the same
session can offer it too.
