fix(serve): silence empty-import-meta esbuild warning

IIFE format leaves import.meta empty, which esbuild warns about for
every consumer of `thatopen serve`. The only triggering code path
in our ecosystem (the @thatopen/fragments worker URL fallback) is
unreachable in practice — all callers go through
FragmentsManager.getWorker(). Silencing the warning removes noise
on every build without hiding any real bug.
