/**
 * Build CacheSafeParams for the side question fork.
 *
 * The preferred source is getLastCacheSafeParams — the exact
 * systemPrompt/userContext/systemContext bytes the main thread sent on its
 * last request (captured in stopHooks). Reusing them guarantees a byte-
 * identical prefix and thus a prompt cache hit. We pair these with the
 * current toolUseContext (for thinkingConfig/tools) and current messages
 * (for up-to-date context).
 *
 * Fallback (first turn before stop hooks fire, or prompt-suggestion
 * disabled): rebuild from scratch. This may miss the cache if the main loop
 * applied buildEffectiveSystemPrompt extras (--agent, --system-prompt,
 * --append-system-prompt, coordinator mode).
