[FEATURE] llm matchers and extractors on non-http protocols

Follow-up to #7733. llm matchers and extractors are wired only for http; other protocols reject them at compile today.

Wire the matchers.LLMMatcher / extractors.LLMExtractor dispatch into the other protocol operators (network, dns, headless, ...), relax the http-only validation, and regenerate jsonschema and docs.
