Subject: [PATCH] fix: strip trailing null bytes from pbxproj before parsing

Some runtimes (notably Bun) and filesystems (APFS) can produce files with
trailing null byte padding. The PEG parser rejects \0 characters, causing
a SyntaxError even though the actual pbxproj content is valid.

Strip trailing null bytes before passing file contents to the parser.
