FlyinPancakeandCopilot Autofix powered by AI 3a9cff9816 feat(metadata): add Moly.hu metadata provider (#1172)
First of all, I don't know if you even want to merge a scraper-based
metadata provider. I made this just for my use-case. If you'd rather
not, I completely understand it.

An alternative would be adopting [Audiobookshelf's Metadata Provider
API](https://audiobookshelf.org/docs/documentation/community/community-providers)
which I contributed to it for exactly the reason to not have scrapers.

## What

Adds [Moly.hu](https://moly.hu) — the Hungarian community book catalog —
as a metadata provider, following the existing provider plugin
architecture (`@register_provider` + settings tab with enable checkbox
and Test Connection button, disabled by default).

## Why

None of the current providers cover Hungarian editions well: Hardcover
and Open Library rarely index them, and Google Books coverage is spotty.
Moly.hu is the de-facto catalog for Hungarian books (local editions
*and* Hungarian translations of foreign works). With this provider,
Universal mode works end-to-end for Hungarian titles: moly search →
localized title/author feed the release search → indexers that carry
Hungarian content can actually match. Related pain points: #595 (books
missing from metadata providers), #1035 (interest in niche sources).

## How

- HTML scraping with BeautifulSoup (already a dependency), no API key
needed
- Scraping approach (search URL, page structure, language-tag mapping)
adapted from the long-lived Calibre `Moly_hu` plugin (GPL v3, credited
in the module docstring), with fallback selector chains inherited from
it
- Sliding-window rate limit (30 req/min) to stay polite to a small
community site
- Standard `@cacheable` decorators; fetch failures return `None` so they
are not cached (same behavior as the Google Books provider)
- Search results carry cover thumbnails, rating and series info as
display fields; `get_book` parses title (zero-width chars stripped,
nested series link excluded), authors, ISBN-13/10, publisher, publish
year, description (spoiler-warning prefix stripped), tags/genres, cover,
and language (from moly's language tags, defaulting to `hu`)
- ISBN search resolves through moly's site search

## Testing

- `tests/metadata/test_moly_parse.py`: offline tests with fixture HTML
mirroring live moly.hu markup — search parsing/dedup, pagination guard,
failure-not-cached behavior, book-page parsing, ISBN resolution, ISBN
validation helper
- `uv run pytest tests/metadata` green (45 passed), `ruff check` / `ruff
format` clean
- Verified live against moly.hu (search, get_book, ISBN lookup) and
running in Docker alongside Hardcover
