/**
 * Response Validator
 *
 * Standalone utility for validating and optionally mutating LLM response text.
 * Handles length checks (including truncation), phrase checks, JSON schema
 * validation, and custom validators.  Returns a structured result telling the
 * caller whether to continue, abort, or retry — the caller owns the retry loop.
 *
 * No async I/O, no telemetry spans, no processor classes.
