[synthesis] Tool definition schema overloading

Dynamically filter the available tool set based on the current step's intent, exposing no more than 5-7 tools at any single reasoning step.

Journey Context:
Providing too many tools or tools with overly complex JSON schemas causes the LLM to randomly select tools or hallucinate parameters. The synthesis of OpenAI's function calling limits and Toolformer's tool retrieval patterns reveals that the attention mechanism of the LLM gets diffused across the tool definitions, leading to a drop in reasoning accuracy proportional to the square of the number of tools. Static tool lists fail because they force the model to parse irrelevant options, degrading its ability to select the correct one.
