"""Tests for neut pub push workflow — generate + upload end-to-end.

Proves:
1. --all collects files from configured folders
2. .md files are auto-generated to .docx via pandoc
3. --headed flag controls browser visibility
4. Missing session prompts user to use --headed
5. Parser accepts all new flags
