new nuitka

[ctoth]

Updates how we handle data files to work with Nuitka's current format and adds deployment mode support. The old format was causing issues with file paths on some systems.

Key changes:

• New data file formatter that handles single files, directories and patterns correctly
• Added deployment mode flag
• Added tests to validate file path handling

The formatter now properly handles:

"file.txt" -> "/abs/path/file.txt=file.txt"
"dir/" -> "/abs/path/dir=dir/"
"dir/*.txt" -> "/abs/path/dir/*.txt=dir/"
