The Claude adapter never registered the Agent SDK's onElicitation callback,
so the SDK declined every MCP elicitation before the user saw it.

Approval-only forms now open the existing mcp-elicitation card with explicit
Cancel, Decline and Approve options and wait for the answer. The form is
filled with the Codex helper, so what counts as approval-only matches Codex,
but schema defaults are never sent since the card doesn't show them. URL
mode and forms asking for values the card can't collect are declined
without a card.
