Fastly does not support wildcard invalidations through its URL-based API, and also does not support invalidating a path prefix like `/dist/`. We are therefore switching to surrogate keys. Requests that match the path `^\/dist\/` get tagged with the surrogate key `/dist/*`, which is then used when invalidating the cache after a release. The tagging implementation can be found in rust-lang/simpleinfra#295.

The cache invalidation on Fastly for releases has been refactored to use surrogate keys instead of paths[^1]. This removes the need to set the static domain for Fastly, but requires passing in the respective service id. The service ids for dev-static and static have already been configured as SSM parameters.
