Cast to ArrayBuffer in image-pipeline worker

steveruizok · steveruizok · commit e2cc53833257 · 2026-02-25T18:38:09.000Z
Add explicit `as ArrayBuffer` type assertions in worker template functions to satisfy TypeScript typings. The changes are limited to templates/image-pipeline/worker/providers/types.ts and templates/image-pipeline/worker/routes/generate.ts and do not alter runtime behavior; they prevent type errors when accessing ArrayBuffer properties.
