/**
 * Go detection — CONTENT-AWARE go.mod classification.
 *
 * A go.mod alone does NOT mean "backend" or "CLI". The same module file backs
 * libraries, HTTP servers (Gin / Echo / Fiber / Chi), CLIs (Cobra), and MCP
 * servers (mcp-go). We read require paths and light layout signals, then branch.
 *
 * Same composition pattern as dart.ts: knowledge in go-detection.json, logic here.
 * Turbo-Cat + scanner both call detectGoProject so they agree by construction.
