llm loses track of plugins when upgraded (with uv and others)

This may not be an llm issue, but could have to do with the interaction of the plugin mechanism with python packaging tooling.

I have llm installed (on MacOS) via uv tool install llm. When I update llm with uv tool upgrade llm, it forgets about all of its installed plugins:

~ > llm plugins                                                                                                                                                                                                                                                                                                                                          
[
  {
    "name": "llm-claude-3",
    "hooks": [
      "register_models"
    ],
    "version": "0.4.1"
  },
  {
    "name": "llm-llamafile",
    "hooks": [
      "register_models"
    ],
    "version": "0.1"
  },
  {
    "name": "llm-perplexity",
    "hooks": [
      "register_models"
    ],
    "version": "0.9"
  },
  {
    "name": "llm-ollama",
    "hooks": [
      "register_commands",
      "register_models"
    ],
    "version": "0.5.0"
  },
  {
    "name": "llm-cmd",
    "hooks": [
      "register_commands"
    ],
    "version": "0.2a0"
  },
  {
    "name": "llm-claude",
    "hooks": [
      "register_models"
    ],
    "version": "0.4.0"
  },
  {
    "name": "llm-mistral",
    "hooks": [
      "register_commands",
      "register_embedding_models",
      "register_models"
    ],
    "version": "0.5"
  }
]

Now I update:

~ > uv tool upgrade llm

Now, no more plugins

~ > llm plugins

Having saved the JSON of plugins, I can re-install them, and it appears that everything is installed from the cache. Is this because llm install is using pip or something similar, and uv handles things differently?

Reproduce the issue with uv tool install llm, llm plugins, and uv tool upgrade llm, comparing plugin discovery before and after the upgrade. Trace how llm installs and discovers plugins in the upgraded environment; done means the listed plugins remain available after upgrading, or the incompatibility with uv is clearly documented.
