Report #54025

[frontier] Prompt engineering changes require redeploying every client instance causing version drift

Centralize prompt templates in MCP server using the prompts capability; clients call prompts/get with runtime parameters to receive optimized system messages

Journey Context:
Instead of hardcoding system prompts in client code, move them to the MCP server as parameterized templates exposed via \`prompts/list\` and \`prompts/get\`. This allows backend teams to optimize prompts \(chain-of-thought examples, tool formatting\) without touching client code, enables A/B testing via prompt versioning on the server, and ensures all clients use canonical prompt templates.
