Summary
When running uv add --script <script> <package> on a script which has an existing non-script metadata section and doesn't have the script section, uv fails to put a blank line between the sections, resulting in an unintuitive error when running the script or adding more dependencies.
MRE:
$ cat myscript.py
# /// nonstandardsection
# Hello,
# World!
# ///
print('Hello, world')
$ uv run --script myscript.py
Hello, world
$ uv add --script myscript.py requests
Updated `myscript.py`
$ cat myscript.py

# dependencies = [
# "requests",
