Functions
void	openswmmvis::io::gdalcaps::ensureRegistered ()
	Idempotently registers all GDAL/OGR drivers (safe to call often).
bool	openswmmvis::io::gdalcaps::driverAvailable (const char *shortName)
	True when a GDAL/OGR driver with this short name is registered.
QStringList	openswmmvis::io::gdalcaps::availableRasterExtensions ()
	Lower-cased, de-duplicated file extensions ("tif", "asc", …) that registered raster drivers report they can open. Sorted.
QStringList	openswmmvis::io::gdalcaps::availableVectorExtensions ()
	availableRasterExtensions() counterpart for vector (OGR) drivers.
QString	openswmmvis::io::gdalcaps::rasterOpenFilter ()
	A QFileDialog filter string for opening raster layers, built from the drivers actually present. "All supported" first, per-format groups next, "All files (*)" last. Formats whose driver is not registered never appear — so the dialog cannot promise a format the build can't open.
QString	openswmmvis::io::gdalcaps::vectorOpenFilter ()
	vectorOpenFilter() counterpart for vector layers.

Runtime GDAL/OGR driver capability probe.

Lets the UI advertise only the formats the compiled GDAL actually registered, instead of a hard-coded literal that can promise drivers (e.g. NetCDF / HDF) a minimal build never included. This honours the project directive to add as few GDAL build modules as possible: the Open dialog filters simply reflect whatever driver set is present, so enabling an optional vcpkg feature later widens them automatically — no code change.
