FileResponseCache class final

A ResponseCache that stores each response as a file in a directory.

File names are the SHA-256 hex digest of the key, so keys of any length and content are safe. The directory is created on first write. Commit the directory to version control, or restore it from a CI cache, to rerun a suite without calling the model.

Writes are atomic: each response goes to a temporary file first and is then moved into place with a rename, so a concurrent reader (including one in another process) never observes a partially written response.
