I forked hugo2nostr and added some features I needed:

• Multi-site support - manage multiple Hugo sites from one config (I publish essays and notes to different sites)

• Image uploads - auto-upload to nostr.build with NIP-98 auth, cached so you don't re-upload

• Preview command - see how your article will look before publishing

• Shortcode processing - converts Hugo shortcodes to markdown

PR submitted upstream.
