[R] ST_Transform fails with 'Can't initialize ProjApi from sedona-proj without proj-sys feature' error

First, thank you very much for this, just started to dig in and looks super cool already.

I am trying to reproduce this Python example: https://sedona.apache.org/latest/blog/2025/09/24/introducing-sedonadb-a-single-node-analytical-database-engine-with-geospatial-as-a-first-class-citizen/#sedonadb-crs-management

But I am getting this error:

Run the provided R reproduction using sedonadb and sf, then trace the ST_Transform path where ProjApi is initialized from sedona-proj. Investigate the reported proj-sys feature error; the issue is done when the example query completes without the initialization failure.
