Research direction
Examine the existing configuration structs in `crates/uv settings/src/lib.rs` and how environment variables like `UV PYTHON INSTALL DIR` are currently handled. Look for the `struct Settings` or similar that maps to `uv.toml` keys. Add a new field for `python install dir` in the appropriate config struct and wire it to read from the TOML file, with fallback to the environment variable. Ensure that the settings merge correctly and update any relevant documentation.
