fix(scripts/lint): pass --no-error-on-unmatched-pattern to oxfmt

When pre-commit lints only files that fall under oxfmt's ignorePatterns
(e.g. .claude/** when only a hook is staged), oxfmt receives a non-empty
file list but its own ignore filter knocks them all out, then exits with
"Expected at least one target file" — blocking the commit.

The flag tells oxfmt to exit 0 with "No files found matching the given
patterns" instead. Matches socket-repo-template/template/scripts/lint.mts
behavior.
