Zanie Blue b9419e67aa Add preview mode and use for warning in uv run (#3192) ... Adds hidden `--preview` / `--no-preview` flags with `UV_PREVIEW` environment variable support. Copies the `PreviewMode` type from Ruff. Does a little bit of extra work to port `uv run` to the new settings model. Note we allow `uv run` invocations without preview and only use its presence to toggle an experimental warning. ## Test plan ``` ❯ cargo run -q -- run --no-workspace -- python --version warning: `uv run` is experimental and may change without warning. Python 3.12.2 ❯ cargo run -q -- run --no-workspace --preview -- python --version Python 3.12.2 ❯ UV_PREVIEW=1 cargo run -q -- run --no-workspace -- python --version Python 3.12.2 ```		2024-04-22 15:41:15 -05:00
