What are the agentic workflow patterns supported in Spring AI?

Prompt Chaining (output feeds the next call), Routing (LLM picks which tool/workflow to invoke), Parallelization (multiple calls in parallel, aggregated), Orchestrator-Subagent (a master LLM delegates to specialized agents), and Evaluator-Optimizer (one LLM generates, another critiques in a loop) — all composed from ChatClient calls and @Tool methods.
