reugenio f09922076f refactor: Rename zpdf to zcatpdf for consistency with zcat* family
- Renamed all references from zpdf to zcatpdf
- Module import: @import("zcatpdf")
- Consistent with zcatui, zcatgui naming convention
- All lowercase per Zig standards

Note: Directory rename (zpdf -> zcatpdf) and Forgejo repo rename
should be done manually after this commit.
