 * lock-step and gives TypeScript a single source of truth for autocomplete
 * / rename support.
 *
 * The `SERVER_` / `BROWSER_` prefixes mirror the tool's primary source
 * (llama-server vs llama-ui). `get_info` is the exception: it is served by
 * the server, but llama-ui falls back to a browser implementation when the
 * server does not provide it, so it can surface under both categories in
 * the UI while keeping a single wire name.
