[GUI Plugin] Extract EPUB Metadata

[ovillo]

Recover fanfic metadata from EPUBs you already have

If FanFicFare can't reach a story anymore: AO3's down, the fic got deleted, or you got the epub someplace else (browser extension, a friend, an old backup), you can end up with a Calibre entry that's just "Title" by Author, none of the fandom/tags/rating/etc. This plugin tries to fix that by reading the metadata straight out of the EPUB itself.

You choose how it writes the data back: straight into Calibre's standard fields, into your own custom columns, or as raw data ready for FanFicFare's own metadata pipeline to process normally.

It also has a separate action for anthology EPUBs (multiple fics bundled together) that recovers each individual story's own completion status, since the bundle's own status usually just tells you if the whole collection is finished or not.

Built mainly around my own workflows: mostly AO3, with support for fanfiction.net (via fichub.net and WebToEpub).

Early beta, mostly vibe-coded, so caveat emptor.

Feedback and suggestions very welcome.
