[Feat] TypeScript 6.0 compatibility via gl-matrix@3.4.4

Target Use Case

react-map-gl is currently not compatible with the upcoming TypeScript 6.0 release.

In Q4 2025, TypeScript 6.0 plans to drop support for module-keyword namespaces.

TypeScript ecosystem testing identified that react-map-gl is not compatible with this change due to a transitive dependency on gl-matrix <3.4.4 that uses legacy namespaces. The dependencies have now all been fixed. So the only remaining work is to bump the versions of those dependencies.

Proposal

react-map-gl has three transitive routes to depend on the problematic gl-matrix:

• A devDependency via mapbox-gl@3.9.0
• A devDependency in modules/react-mapbox via mapbox-gl: ^3.9.0
• A devDependency in modules/react-maplibre via maplibre-gl: ^5.0.0

The following package versions have already been made compatible with TS 6.0:

• gl-matrix@3.4.4
• mapbox-gl@3.15.0
• maplibre-gl@5.7.0

Please bump the existing dependencies to use these minimum versions.

TypeScript has now merged the removal of the module keyword in both *.ts and *.d.ts files. It will land in the next release which is TS 6.0.

So the impact here goes up from a likelihood to an imminent certainty. The remedy is simple and described in the OP which is to bump three dependencies. I recommend doing this soon.
