agent terminal: show full body for send tool calls

send was truncating to 80 chars in the tool_use row, hiding
anything past the first sentence. now renders as a collapsed
<details> like Write/Edit — summary still shows the recipient +
headline (so the operator can scan), expanding reveals the full
body unchanged.

recv side was already covered: the wake prompt shows the full
incoming body, and explicit recv() tool_result rows expand to
the full text via the existing collapsed-results path.
