Review comments at @packages/py/img2num/cli.py:
- Line 11: Update the output default in the CLI argument handling so it is
derived from image_path, placing the generated SVG beside the input with the
input’s base name; preserve any explicitly supplied -o/--output value unchanged.
- Around line 10-11: Update the CLI argument handling and image/output
processing to support multiple input paths and iterate over each input, while
preserving the existing single-image behavior. Treat `-` as stdin for image
input and stdout for SVG output, using stream-compatible image and output
handling instead of filesystem-only `Image.open` and `open` calls.
- Line 46: Update the CLI output handling around `args.output` to reject an
existing destination unless the user explicitly requests overwrite, and reject
destinations that resolve to the input image path. Perform both checks before
opening the output so the input or an existing file is never truncated
unintentionally.

- Around line 87-88: Update output-path construction in the batch flow near
`image_path` so distinct input subdirectories produce distinct SVG output paths,
preserving each image’s path relative to the input directory. Keep the existing
filename extension conversion and `--overwrite` behavior.
- Line 79: Update both output-type mismatch branches in the CLI flow to
terminate with a nonzero status, using parser.error or an explicit nonzero exit
instead of exit(). Keep the existing mismatch checks and error messages intact.

Reject an output path that names the input image.
If a user runs img2num input.png -o input.png --overwrite, convert loads the image and this write replaces it with SVG text. Check input/output identity before conversion, including filesystem aliases. A prior review flagged this input-destruction path, but the current code still permits it.

Accept a single glob match as a single file.
If photos/*.jpg matches one image, single_file is false because the glob expression is not a file. img2num 'photos/*.jpg' -o result.svg then rejects a valid single-image conversion. Determine this case from the expanded job and its source.

Check collisions for default output paths.
If the inputs are photo.jpg and photo.png in one directory, both default outputs are photo.svg. The second conversion is skipped, or replaces the first with --overwrite. Apply the planned-output collision check before returning these jobs. A prior review flagged the same collision risk for batch output.

Detect output aliases on case-insensitive macOS volumes.
On a case-insensitive APFS volume, A.png and a.jpg can coexist, but their planned A.svg and a.svg paths name the same file. os.path.normcase leaves case unchanged on macOS, so this check accepts both jobs. The second job skips or overwrites the first. Compare planned paths using a collision rule that accounts for the output volume’s case behavior. (docs.python.org)
