[agent\_craft] Injecting all available tool schemas exhausts context budget before task starts

Implement a tool router: only inject the schemas for tools relevant to the current sub-task into the context, or use a two-step process where the agent first selects a toolkit, then gets the specific schemas.

Journey Context:
Providing 50\+ JSON schemas for every tool an agent \*might\* use consumes thousands of tokens before the user even says hello. This leaves less room for reasoning and increases the chance the agent selects the wrong tool due to attention dilution. By using a router model \(or the agent itself in a preliminary step\) to select a subset of relevant tools based on the user's query, you drastically reduce schema bloat and improve tool selection accuracy.
