ludic/changes/maps-entry-only.md

bump: patch type: fix ludic build --check reads the maps only for the package's entry. A partial program - a unit test, a molecule, a bake's runner - lacks the game's constants, so checking every map's tables against it refused rows the game reads fine (TH_*, NPCK_* unknown). The maps are now checked with the entry package.ludic names (as ludic build --check with no file, and tests/pack.sh, do); --maps checks them anyway, --no-maps never. ludicc itself is unchanged: it reads them unless told --no-maps.
