Automatically set uv to use the active Conda environment

Miniconda is still the simplest way to install Cuda, and the easiest way to have multiple versions of Cuda on one machine.

uv doesn't use the active Conda enviroment for uv sync like it does for uv pip, but we can fix that with a rc script:

# Function to update UV_PROJECT_ENVIRONMENT when Conda environment changes
conda_auto_env() {
    if [[ -n "$CONDA_PREFIX" ]]; then
        export UV_PROJECT_ENVIRONMENT="$CONDA_PREFIX"
    else
        unset UV_PROJECT_ENVIRONMENT
    fi
}

# Run the function initially to set the variable immediately
conda_auto_env

# Hook into shell prompts
if [[ -n "$ZSH_VERSION" ]]; then
    # Ensure add-zsh-hook is available
    autoload -Uz add-zsh-hook
    # Avoid duplicate hooks
    if ! [[ -v _conda_update_hook_added ]]; then
        add-zsh-hook precmd conda_auto_env
        _conda_update_hook_added=1
    fi
elif [[ -n "$BASH_VERSION" ]]; then
    # Ensure PROMPT_COMMAND is updated only once
    if [[ -z "$PROMPT_COMMAND" ]]; then
        PROMPT_COMMAND="conda_auto_env"
    elif [[ "$PROMPT_COMMAND" != *"conda_auto_env"* ]]; then
        PROMPT_COMMAND="conda_auto_env; $PROMPT_COMMAND"
    fi
fi

Note that this may clash with future uv updates with uv and you might need to remove it.
