Test cache against latest release in CI

[zanieb]

Detect cache incompatibility issues like #2711 by testing against the last version of uv continuously

I think this is a decent sanity check. I wonder if it might be better to install something bigger like homeassistant to get a bigger sampling of packages.

This won't catch silent errors, but I think it will at least catch some subset of errors that rkyv validation doesn't catch.

I'll test homeassistant and choose something prudent for test suite runtime

Yeah, it looks like getting a broader sampling here matters. Things are hunky dory with anyio:

$ uv cache clean && rm -rf .venv
Clearing cache at: /home/andrew/.cache/uv
Removed 41594 files (246.2MiB)

$ uv-0.1.24 venv
Using Python 3.12.0 interpreter at: /home/andrew/.pyenv/versions/3.12.0/bin/python3
Creating virtualenv at: .venv
Activate with: source .venv/bin/activate

$ uv-0.1.24 pip install anyio
Resolved 3 packages in 80ms
Downloaded 3 packages in 23ms
Installed 3 packages in 5ms
 + anyio==4.3.0
 + idna==3.6
 + sniffio==1.3.1

$ uv-0.1.25 pip install anyio --reinstall-package anyio
Resolved 3 packages in 25ms
Installed 1 package in 6ms
 - anyio==4.3.0
 + anyio==4.3.0

But homeassistant lets me repro:

$ uv cache clean && rm -rf .venv
Clearing cache at: /home/andrew/.cache/uv
Removed 41598 files (246.2MiB)

$ uv-0.1.24 venv
Using Python 3.12.0 interpreter at: /home/andrew/.pyenv/versions/3.12.0/bin/python3
Creating virtualenv at: .venv
Activate with: source .venv/bin/activate

$ uv-0.1.24 pip install -q homeassistant

$ uv-0.1.25 pip install -q homeassistant --reinstall-package homeassistant
error: Failed to download and build: pyric==0.1.6.3
  Caused by: Failed to deserialize cache entry
  Caused by: expected version to start with a number, but no leading ASCII digits were found

This LGTM.
