The previous implementation exposes arbitrary user input to the cache as an identifier, which is highly error-prone and can cause the cache to enter an inconsistent state if the user is not careful. This change replaces the implementation to compute identifier late, using url string as params.

This moves all cache I/O code to Cache. Artifact now only contains methods for constructing their actual contents.

This must be writable to enable renaming, and the final result is conventionally read-only alongside the entire directory contents. This change overrides the permission bits as part of Store.

This is still not ideal as it makes entry into Store sequential. This will be improved after more usage code is written.

This works on any directories and should be robust against any bad state the artifact curing process might have failed at.

This provides infrastructure for computing a deterministic identifier based on current artifact kind, opaque parameters data, and optional dependency kind and identifiers.
