fix(docs): use dedicated package script instead of inline task

The docs:package task in mise.toml was trying to package files that didn't
exist (markdown/API.md and README.md in docs/api/). Replaced the inline
script with a call to the existing package.sh script which properly packages
the HTML documentation.

The package.sh script correctly:
- Validates documentation exists before packaging
- Packages only the HTML documentation that's actually generated
- Creates both .tar.gz and .zip archives for distribution
