git-tag cache-keys not working if there are tags containing slash

[snizovtsev]

I use slashes in git tags to separate workspace member from version, like:

$ git tag -l
py-consul/v1.5.3.post0
xyz

gives "1.5.3.post0" version to workspace member workspace/py-consul.

As so, I've each workspace member's pyproject.toml looks like this:

[project]
name = "py-consul"
dynamic = ["version", "x-run-hook"]

[tool.uv]
cache-keys = [{ git = { commit = true, tags = true } }, { file = "pyproject.toml" }]

[tool.hatch.version]
source = "my-plugin"

However I noticed uv won't bump my project version when I add or remove a second tag like xyz. It echos the following error in DEBUG log:

DEBUG Failed to read the current tags: failed to read from file `my-project/.git/refs/tags/py-consul`: Is a directory (os error 21)

Obviously, uv should be improved to walk entire .git/refs/tags directory instead of reading flat structure as it done now.

If nobody objects, I want to use this issue as my practice in Rust and plan to work on a fix in a next few days.
