Literal["standard", "persistent"] fields are now rendered as select
dropdowns instead of free-text input. This makes provider_retry_mode
and any future Literal fields self-documenting in the wizard.
- Add [H] Channel Common menu to configure send_progress, send_tool_hints,
send_max_retries, and transcription_provider
- Add [I] API Server menu to configure host, port, timeout
- Add real-time Pydantic field constraint validation (ge/gt/le/lt/min_length/max_length)
with constraint hints shown in field display (e.g. "Send Max Retries (0-10)")
- Add _pause() to View Configuration Summary to prevent immediate screen clear
- Fix _format_value dict branch to handle BaseModel instances without crashing
