[agent\_craft] Agent context window consumed by massive JSON schemas for hundreds of tools

Implement a tool router: only inject the schemas for tools relevant to the current sub-task into the prompt, rather than all available tools.

Journey Context:
Providing 50\+ tool schemas in the system prompt works for simple tasks, but as the number grows, the model suffers from choice paralysis, increases latency, and wastes context tokens. A semantic router or intent classifier can select a subset of tools \(e.g., 3-5\) to expose for the current step, keeping the context lean and focused.
