fix(frontend): restore the two rolldown bindings npm dropped from the lockfile

The from-scratch lockfile regeneration in b9eda09d bumped rolldown 1.2.4 ->
1.2.5 but wrote back only 14 of its 16 optional platform bindings: npm
removed the old @rolldown/binding-darwin-x64 and
@rolldown/binding-linux-arm64-gnu entries and never added the 1.2.5 ones.
Both are still listed in rolldown's optionalDependencies, so the packages
section no longer matches the dependency graph.

npm ci validates the whole ideal tree, not just the packages installable on
the current platform, so it aborted with EUSAGE everywhere and took down all
four workflows that install the frontend - CI, Release, CodeQL and Docs
Deploy - each at its first npm ci step. The Go jobs were unaffected.

Regenerated with a clean npm install --package-lock-only, which resolves from
registry metadata alone and keeps every optional binding regardless of the
host platform. The diff is purely additive - the two missing blocks, no
version changes.
