In local mode (default), the server communicates via stdio, making it
suitable for use as an OpenCode skill.

In remote mode (--remote flag), the server listens on HTTP and exposes
a REST API for multi-user access.

Examples:
  devour serve                    # Local mode (stdio)
  devour serve --remote           # Remote mode on default port
  devour serve --remote --port 3000`,
	RunE: runServe,

	serveCmd.Flags().IntVarP(&servePort, "port", "p", 8080, "HTTP port (remote mode only)")
