/**
 * `gsk mesh` — thin proxy to the native gsk-mesh binary.
 *
 * gsk-mesh is a standalone native Rust binary (Genspark Mesh: Tailscale-based
 * private networking + SSH). `gsk mesh <args...>` lazily downloads + verifies
 * it on first use, then exec's it with the remaining argv. Auth is shared:
 * gsk-mesh reads the same ~/.genspark-tool-cli/config.json `api_key` that
 * `gsk login` writes.
 *
 * Why this is intercepted OUTSIDE commander (see index.ts main()): a true
 * passthrough needs commander's `passThroughOptions`, which requires
 * `enablePositionalOptions` on the program — and that flips global option
 * parsing for the WHOLE CLI (`gsk web_search q --debug` would break). So we
 * detect `mesh` by scanning argv ourselves and forward everything verbatim,
 * leaving the rest of the CLI's parsing untouched. The stub command registered
 * by `registerMeshCommand` exists only so `mesh` shows up in `gsk --help`.
 */
