Returns TRUE if the user is authenticated with Google Earth Engine
via rgee, without triggering any interactive prompts.
If conda is provided, the function first tries to bind that Conda
environment non-interactively (CRAN-safe), then checks credentials.
check_rgee_ready(conda = NULL, verbose = interactive())Logical, invisibly: TRUE if ready, FALSE otherwise.
[optional] (character) Name of a Conda environment to bind via
reticulate::use_condaenv() before checking credentials. If
NULL (default), the current reticulate binding is used.
[optional] (logical) If TRUE, prints a short diagnostic
message when GEE is not ready. Defaults to interactive() so CRAN/CI
stays quiet.
