Report #30752

[frontier] Agent and MCP server drift out of sync on supported workflows and prompt versions

Discover and render MCP prompts using \`prompts/list\` and \`prompts/get\` to obtain server-provided workflow templates with versioned arguments instead of hardcoding prompts in the client.

Journey Context:
Hardcoding 'You are a helpful assistant that uses the git server to...' in the agent code creates version drift when the server updates its capabilities or intended workflows. Natural language descriptions of workflows are ambiguous and lead to inconsistent usage. MCP Prompts allow the server to expose templated workflows \(like 'analyze\_code' or 'security\_audit'\) with typed arguments \(e.g., file\_path, severity\_threshold\). The client discovers these via \`prompts/list\`, retrieves the template via \`prompts/get\` with arguments rendered, and uses the result as the system prompt or user message. This ensures the agent uses the server's intended interaction patterns, handles versioning automatically through the discovery mechanism, and allows complex multi-step workflows to be encapsulated server-side without client knowledge of the internals.
