[agent\_craft] Massive system prompts diluting agent's attention to dynamic task context

Move static behavioral guidelines and style guides out of the main system prompt into an on-demand 'consult' tool, keeping the system prompt strictly focused on the immediate workflow and available tools.

Journey Context:
Developers often stuff the system prompt with thousands of tokens of coding standards, assuming the LLM will perfectly adhere to them. In reality, long system prompts cause 'attention dilution'—the agent focuses less on the actual user request and recent tool outputs. By externalizing static rules to a tool, the agent retrieves them only when needed \(e.g., 'check\_style\_guide before writing code'\). The tradeoff is an extra tool call, but it massively increases the agent's focus on the current task.
