Extends the Inquirex DSL with four LLM-powered verbs — clarify, describe, summarize, and detour — that run server-side to extract structured data, generate text, and dynamically branch flows. Pluggable adapter interface keeps the gem LLM-agnostic; a NullAdapter ships for testing.

Enriches Inquirex flow definitions with framework-agnostic widget rendering metadata. Adds `widget` and `widget_mobile` DSL verbs that attach WidgetHint objects to nodes. Consumed by inquirex-tty, inquirex-js, and inquirex-rails adapters. Produces enriched JSON — no HTML or JavaScript generated.
