Wrap unsafe script shebangs in /bin/sh (#2097) 
## Summary

This is based on Pradyun's installer branch
(d01624e5f2/src/installer/scripts.py (L54)),
which is itself based on pip
(0ad4c94be7/src/pip/_vendor/distlib/scripts.py (L136)).

The gist of it is: on Posix platforms, if a path contains a space (or is
too long), we wrap the shebang in a `/bin/sh` invocation.

Closes https://github.com/astral-sh/uv/issues/2076.

## Test Plan

```
❯ cargo run venv "foo"
    Finished dev [unoptimized + debuginfo] target(s) in 0.14s
     Running `target/debug/uv venv foo`
Using Python 3.12.0 interpreter at: /Users/crmarsh/.local/share/rtx/installs/python/3.12.0/bin/python3
Creating virtualenv at: foo
Activate with: source foo/bin/activate

❯ source "foo bar/bin/activate"

❯ which black
black not found

❯ cargo run pip install black

Readme.md

Reimplementation of wheel installing in rust. Supports both classical venvs and monotrail.

There are simple python bindings:

from install_wheel_rs import LockedVenv

locked_venv = LockedVenv("path/to/.venv")
locked_venv.install_wheel("path/to/some_tagged_wheel.whl")

and there's only one function: install_wheels_venv(wheels: List[str], venv: str), where wheels is a list of paths to wheel files and venv is the location of the venv to install the packages in.

See monotrail for benchmarks.
