`mise use --global [email protected]` copies virtualenv configuration from current directory

[rouge8]

Describe the bug

When I run mise use --global [email protected] from a directory with a mise.toml and a virtualenv configuration, mise copies the virtualenv configuration to the global Python which is definitely not what I want/expect.

To Reproduce

❯ cat mise.toml 
[tools]
python = {version="3.13.0", virtualenv=".ve"}
❯ mise trust
mise trusted /Users/andyfreeland/tmp/mise-venv-bug/mise.toml
mise WARN  no venv found at: ~/tmp/mise-venv-bug/.ve

To create a virtualenv manually, run:
python -m venv ~/tmp/mise-venv-bug/.ve
❯ mise use --global [email protected]
mise hint use multiple versions simultaneously with mise use [email protected] [email protected]
mise WARN  python is defined in ~/tmp/mise-venv-bug/mise.toml which overrides the global config (~/.config/mise/config.toml)
mise ~/.config/mise/config.toml tools: [email protected]
mise WARN  no venv found at: ~/tmp/mise-venv-bug/.ve

To create a virtualenv manually, run:
python -m venv ~/tmp/mise-venv-bug/.ve
❯ cat ~/.config/mise/config.toml
[tools]
python = { version = "3.13", virtualenv = ".ve" }

[settings]
experimental = true

Expected behavior

The virtualenv setting should not affect the global config.
