Description

Unless I missed it, I think currently there is no way to limit the cache size.

I think this would be valuable in ci self-hosted runners where the cache can grow pretty big due to the need to support many python versions packages downloads, we have seen it growing up to ~40GB.

E.g. sccache has a SCCACHE_CACHE_SIZE that sets a maximum size of the cache.

At the moment, if it grows to big you run uv cache clean and start over the game again, but with a cache size limit one wouldn't have to worry.

What do you think?

PS.: thanks for making pip installs great again

Contributor guide

Research direction
Add a cache size limit configuration (e.g., environment variable UV CACHE SIZE or CLI flag). The cache should be pruned when exceeding the limit using an LRU or similar eviction policy. Implement tests and documentation.
