Fix artifact upload: include-hidden-files for .claude-issues/

upload-artifact@v6 excludes hidden directories (starting with .)
by default since Sep 2024. Since .claude-issues/ is a dot-directory,
all files were silently skipped. Adding include-hidden-files: true
fixes the "No files were found" warning.
