/**
 * XLN CLI Entry Point
 *
 * This is the main entry point to run xln server.
 * Runtime is a pure library with no side effects.
 * Uses BrowserVM by default (external RPC not yet supported).
 *
 * Usage:
 *   bun run xln.ts              → start server with BrowserVM
 *   NO_DEMO=1 bun run xln.ts    → start server without demo prompt
 *   bun run xln.ts --no-demo    → same as above
