Initialises Julia against the pinned Julia project the package ships in `inst/julia`, and loads the bridge code. Idempotent: subsequent calls are no-ops once setup has succeeded. Heavy lifting is delegated to [juliabridge::julia_ready()] and [juliabridge::julia_load_bridge()].
setup_ForecastBaselines(verbose = TRUE)Invisibly returns `TRUE` if setup succeeded.
Note: this is *not* called from `.onLoad`. Eager Julia initialisation on package load can crash R during attach when interacting with other compiled backends (e.g. Stan). Call this function explicitly, or rely on the lazy [check_setup()] guard inside the package's exported functions.
