Workflow

1. Identify the input(s) from the user message — each input may be a file, a directory, or a quoted glob mask.
2. Run scripts/clean.sh <input> [<input>...]. Outputs are always written next to each input as <slug>-clean.<ext>; you do not need to pick output paths.
3. Report the final written file path(s).

Flags:

• -r / --recursive — recurse into subdirectories when an input is a directory.
• -f / --overwrite — overwrite existing <slug>-clean.<ext> outputs (default: skipped).

Examples:

scripts/clean.sh ./foo.png                 # single file
scripts/clean.sh ./photos                  # whole folder (non-recursive)
scripts/clean.sh -r ./photos               # recurse into subfolders
scripts/clean.sh './photos/IMG_*.png'      # glob mask (quote it)
scripts/clean.sh -f ./photos               # overwrite existing *-clean.* outputs

Files whose basename already ends in -clean and existing <slug>-clean.<ext> outputs are skipped by default.

The script auto-installs @pilio/gemini-watermark-remover globally on first run if gwr is not on PATH. If npm's global bin directory is not on PATH, the script prints the directory and exits — instruct the user to add it to PATH and retry.
