Subject: [PATCH 1/2] Stop caching dist-newstyle in the release build

The release cache restored the whole dist-newstyle directory keyed
only on the dependency freeze file, so a stale local package build
(including its inplace package registration) could be reused even
after the source or the package version changed. Cache only the
external Cabal store; local packages build fresh every run.

Subject: [PATCH 2/2] Stop caching dist-newstyle in CI and future-proofing
 builds too

Same stale-cache risk as the release build: keying the cache only on
the freeze file lets a stale local package build, including its
inplace package registration, survive a source or version change.
