[synthesis] Agent experiences tool choice paralysis and selects wrong tools when presented with a flat list of dozens of tools

Implement a two-stage tool retrieval process: first use semantic search to select 3-5 relevant tools based on the current sub-goal, then present only those to the LLM for choice.

Journey Context:
LLMs suffer from lost in the middle and decision fatigue. When given 50 tools in a flat schema, they often pick the wrong one or hallucinate parameters because the attention mechanism is spread too thin. People think more tools equals more capability. The tradeoff is that a retrieval step adds latency, but it dramatically increases tool selection accuracy and reduces token usage.
