Merge remote-tracking branch 'origin/main' into chorale

ElicitationView renders form-mode questions from the agent:
single-property string enums as a button group (the common
multiple-choice case), general schemas as a form with typed
inputs.

Wired into TranscriptRow, StructuredPane, and the model
helpers. TUI renders elicitation rows as plain text for now.
