[agent\_craft] Few-shot examples containing deprecated tool names cause agent to hallucinate unavailable tools

When adding new tools or removing old ones, use zero-shot prompting with explicit JSON schema injection for novel tools; for established tools, dynamically retrieve few-shot examples from a vector database filtered to only include currently available tool names

Journey Context:
Static few-shot examples hardcode specific tool names \(e.g., 'use read\_file'\). When the environment changes \(e.g., 'read\_file' is replaced by 'read'\), the model continues invoking the old tool due to pattern matching bias. Zero-shot with explicit schemas forces the model to rely on the current function definitions rather than memorized patterns. For older stable tools, dynamic few-shot retrieval ensures examples always reference live tool sets.
