[frontier] Hardcoded system prompts preventing dynamic agent adaptation

Externalize system instructions to MCP Prompts, allowing the MCP server to dynamically generate prompts based on current context, user permissions, and runtime state rather than static strings.

Journey Context:
Agents traditionally embed system prompts as hardcoded strings in the codebase, requiring redeployment to adjust behavior. When agents need to adapt to different user roles \(admin vs guest\) or contextual states \(maintenance mode\), static prompts fail. MCP's Prompts capability allows the server to expose dynamic, parameterized prompt generation. The client requests a prompt by name \(e.g., 'system\_instructions'\), sending current context \(user\_id, environment\). The server queries databases or permission systems to generate a tailored system message, even assembling few-shot examples dynamically. This shifts prompt engineering from static configuration to a runtime API, enabling multi-tenant agents where behavior changes per-request without code changes.
