Erik JohnstonandClaude Fable 5.1 74f5fbf306 Let a Rust cache mirror a Python cache's invalidations ...

The sync store's caches are copies of `@cached` functions of the
datastore, and those are invalidated by several paths: a write on the
process, the caches stream, and the current state batch. Rather than tap
each path, a `DeferredCache` now takes mirrors, invalidated with its own
keys whenever it is, and `mirror_rust_cache` attaches a Rust cache as one,
passing the key as the tuple of arguments.

A `tree=True` cache is invalidated by a prefix of its key as well, so the
Rust cache gains `invalidate_matching`, which drops every entry whose key
satisfies a test, and a key type can decode a prefix into one. A key of
two strings, such as room and user, does.
