/**
 * tests/unit/cli-setup-opencode.test.ts
 *
 * `omniroute setup opencode` wires the bundled @omniroute/opencode-plugin into a
 * local OpenCode install: copies the built plugin into `<config>/plugins/omniroute/`
 * and registers a tuple entry in `opencode.json` (idempotent, replacing the legacy
 * `opencode-omniroute-auth` entry from issue #3711).
 *
 * The command resolves the bundled plugin at module load, so the
 * OMNIROUTE_OPENCODE_PLUGIN_DIR fixture override MUST be set before the import.
 * `opts.configDir` keeps the test off the real OpenCode config dir on every platform.
