Replaces internal/garmin's MCP-based mcp-garmin integration with a custom
newline-delimited-JSON subprocess protocol around python-garminconnect
directly, folded into this repo. MCP's dynamic tool-discovery value is
unused here (fixed call sites, no LLM choosing tools), and both projects
are owned by the same person, so the extra protocol layer and two SDK
dependencies (mcp-go, mcp[cli]) were pure overhead -- especially given
plans to containerize the backend.
