Support Running Without Triggering npm pack | postbuild support

[holblin]

Description:

It would be helpful to allow the tool to run directly on the current folder without automatically triggering npm pack.

Use Case:

I want to use this tool as part of a postbuild script. However, the current behavior causes an infinite loop:

• npm postbuild triggers attw
• attw triggers npm pack
• npm pack triggers npm build
• npm build triggers npm postbuild
• ...and the cycle repeats

Current Workaround:

To avoid this loop, I manually create a tarball and run attw on it:

"postbuild": "tar -czf dist/archive.tgz LICENSE README.md dist/cjs dist/esm dist/umd docs package.json && npx attw --format ascii dist/archive.tgz && rm dist/archive.tgz"

Proposed Solution:

Introduce an option or flag to allow attw to operate directly on the current directory without invoking npm pack.
