Display pending local and server changes for a Mergin project directory.
Wraps mergin status from the mergin-client CLI. Run before rfp_mergin_sync()
to preview what will be uploaded.
Details
Note: a segfault on mergin status is a known issue after schema changes
(e.g., adding columns to a gpkg). If status segfaults, just call
rfp_mergin_pull() then rfp_mergin_push() directly.
