Cache conda packages per subdir - #557

Conversation
Conda download caching keyed artifacts on channel, name, version and filename only, but the same filename can hold different bytes in each subdir (python_abi-3.11-4_cp311.conda in linux-64 and osx-arm64, for example). A client on one platform could be served another platform's package. The subdir is now part of the cached filename, so each one gets its own entry. Entries cached under the old key are no longer used and are re-fetched on first request.

The conda cache key left out the subdir, so the same filename under
linux-64andosx-arm64shared one entry. Many conda filenames are identical across subdirs, so a client could get another platform's package.Artifacts are now cached as
{subdir}/{filename}, the way apk and arch already do it. Old entries are no longer matched and get fetched again on first use. Denylist, cooldown and retention still work on name and version.
