/**
 * Extension dialogs as ACP form elicitations.
 *
 * T3 v0.1.6 renders a form only from `requestedSchema.properties`: a string enum becomes single
 * choice, a boolean becomes `"true"`/`"false"` rows, and any other property is free text. It
 * ignores `required`, `default`, `oneOf`, `items`, masking and schema-level titles, and it has no
 * decline control and no timeout. So only the four dialog methods below map, each as exactly one
 * property; multiselect, secret inputs and dialogs without an answer stay cancelled by the
 * adapter. Answers arrive as strings and are validated here before they reach the child.
 *
 * Never attach `_meta.codex_approval_kind` or use a `mcp_tool_call_approval_` request id: T3
 * auto-accepts that shape before rendering a form.
