/**
 * MockThinkingHandler — canonical example for the v2.14 ThinkingHandler
 * contract. Used by:
 *
 *   1. Tests — drives the shared contract test (every shipped handler
 *      MUST satisfy the same invariants this mock demonstrates).
 *   2. Future provider authors — reference implementation showing how
 *      to handle BOTH Anthropic-shape inputs (signed blocks, possibly
 *      redacted) and OpenAI-shape inputs (multi-block summary). The
 *      pattern of "discriminate by shape, normalize each branch" is
 *      reusable across providers.
 *   3. The MockProvider for end-to-end tests of the framework wiring
 *      without depending on a real LLM SDK.
 *
 * Defaults are deliberately sensitive-data-free — no fake PII, no
 * fake-signature material that could be confused for real cryptography,
 * no internal-looking IDs. Sets the example for consumer-authored
 * handlers.
