Summary

When updating inline script metadata of a python script via uv add --script, user's comments after the script-comment-block are deleted.

Reproducer:

Create python script foo.py with contents:

# /// script
# requires-python = ">=3.13"
# dependencies = [
#     "numpy",
# ]
# ///
#
# Some description

Run uv add --script test.py matplotlib. foo.py:

# /// script
# requires-python = ">=3.13"
# dependencies = [
#     "matplotlib",
#     "numpy",
# ]
# ///

As you can see, # Some description has been deleted by uv, even though it is placed after the closing # /// of the script-block.

Adding an empy line (no leading #) helps to preserve the user-comment, but I believe that uv should not touch anything outside the block-boundaries.
