commit ac50b1860aafaa3aa7dbc24466db64d01b1ea88a
Merge: 5de061ff1 4e5b21e1b

Merge pull request 'docs: document GMP build dependency' (!726) from Komzpa/postgis:codex/ticket-6112-readme-gmp into master
README.postgis now documents the current build dependency contract and points readers at the generated compatibility browser for the maintained support matrix. It updates PostgreSQL 14+, libgmp-dev and pkg-config in the apt dependency example, GDAL 2.4+ for raster builds, SFCGAL minimum/full-feature wording, and the compatibility-browser-derived iconv, gettext, protobuf-c, and GTK classifications.
The same dependency-version sweep also updates current manual/release docs: NEWS records the #6112 README dependency documentation fix for 3.7.0rc1, doc/postgis.xml carries the current PostgreSQL and GEOS entity values, installation docs align GEOS/GDAL/SFCGAL wording, release_notes.xml uses PostgreSQL 19beta2, and the dependency guard example uses the current SFCGAL 2.3 threshold.
