From PEP 517:
> All command-line scripts provided by the build-required packages must
be present in the build environment’s PATH. For example, if a project
declares a build-requirement on flit, then the following must work as a
mechanism for running the flit command-line tool:
>
> ```python
> import subprocess
> import shutil
> subprocess.check_call([shutil.which("flit"), ...])
> ```

❯ uv run python -c "import uv; uv.build_sdist"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/zb/workspace/uv/python/uv/__init__.py", line 45, in __getattr__
raise AttributeError(err)
AttributeError: Using `uv.build_sdist` is not allowed. The uv build backend requires preview mode to be
enabled, e.g., via the `UV_PREVIEW=1` environment variable.
❯ uv run python -c "import uv; uv.foo"
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/zb/workspace/uv/python/uv/__init__.py", line 48, in __getattr__
raise AttributeError(err)
AttributeError: module 'uv' has no attribute 'foo'
❯ uv run python -c "import uv; uv.find_uv_bin"
```
It used to report:
```
» mypy
python/uv/_build_backend.py:40: error: Incompatible types in assignment (expression has type "list[str]", variable has type "CompletedProcess[bytes]") [assignment]
python/uv/_build_backend.py:41: error: Value of type "CompletedProcess[bytes]" is not indexable [index]
python/uv/_build_backend.py:46: error: Value of type "CompletedProcess[bytes]" is not indexable [index]
Found 3 errors in 1 file (checked 6 source files)
```
So, I had to fix this problem by renaming the `result` var.

## Summary
[ruff's `find_bin`
implementation](19cd9d7d8a/python/ruff/__main__.py (L31))
can find the binary in relative to the package root. It'd be nice to
have the same functionality for `uv`.
Closes#2222
Closes https://github.com/astral-sh/uv/issues/2058
Replaces https://github.com/astral-sh/uv/pull/2338

We use an environment variable (`UV_INTERNAL__PARENT_INTERPRETER`) to
track the invoking interpreter when `python -m uv` is used. The parent
interpreter is preferred over all other sources (though it will be
skipped if it does not meet a `--python` request or if `--system` is
used and it belongs to a virtual environment). We warn if `--system` is
not provided and this interpreter would mutate system packages, but
allow it.
Add a single job for for fast lint tools. Rustfmt for rust, ruff for
python formatting and linting, prettier avoids inconsistent formatter
changes between pycharm and vscode.
First, replace all usages in files in-place. I used my editor for this.
If someone wants to add a one-liner that'd be fun.
Then, update directory and file names:
```
# Run twice for nested directories
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
find . -type d -print0 | xargs -0 rename s/puffin/uv/g
# Update files
find . -type f -print0 | xargs -0 rename s/puffin/uv/g
```
Then add all the files again
```
# Add all the files again
git add crates
git add python/uv
# This one needs a force-add
git add -f crates/uv-trampoline
```
## Summary
This PR adds a release workflow powered by `cargo-dist`. It's similar to
the version that's PR'd in Ruff
(https://github.com/astral-sh/ruff/pull/9559), with the exception that
it doesn't include the Docker build or the "update dependents" step for
pre-commit.
