What this skill does
Find the latest version of Mediabunny with npm view mediabunny version. In the root package.json, update the catalog versions for mediabunny, @mediabunny/mp3-encoder, and @mediabunny/ac3 to that version. In packages/template-/package.json, update mediabunny and any @mediabunny/ packages to the same version. Templates use explicit versions, not catalog:, so update them manually. Update packages/cli/src/extra-packages.ts with the new Mediabunny version. Update packages/studio-shared/src/package-info.ts with the new Mediabunny version in extraPackages. Update the compatibility table in packages/docs/docs/mediabunny/version.mdx. To find the next version this upgrade will be applied to, look in the root package.json for the version and increment the patch version by 1. Run bun i at the end.
