fix(pre-commit): exclude lockfiles from oxfmt-frontend to avoid hard-erroring on lockfile-only diffs

The oxfmt-frontend hook's `files:` regex matches `.json`, which includes
package-lock.json. oxfmt itself internally treats lockfiles as generated
files and filters them out of its target list, so when a diff touches
only a lockfile, pre-commit hands oxfmt a target list that resolves to
zero real files. Unlike prettier (which no-ops cleanly on an empty
target set), oxfmt hard-errors with "Expected at least one target
file. All matched files may have been excluded by ignore rules." and
exits 2.

This masqueraded as a red CI check on any lockfile-only PR, most
immediately dependabot bump #42718, and will recur on every future
lockfile-only dependency bump until fixed on master.

Add an `exclude:` pattern for package-lock.json, yarn.lock, and
pnpm-lock.yaml so pre-commit never hands oxfmt a target set doomed to
be empty. Real frontend source files are unaffected - verified with
`pre-commit run oxfmt-frontend --files <path>` against a lockfile-only
target (now skips cleanly), a real .ts file (still formats), and a
mixed lockfile + real file target (still formats the real file).
