Subject: [PATCH] refactor: Rename zpdf to zcatpdf for consistency with zcat*
 family
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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.
