fix(french): rewrite Chireads, repoint Ligh Novel FR, drop dead MassNovel and MTL Novel (FR)

[Balrog57]

PR description

Fixes the broken French sources in LNReader, adapting each plugin to the current state of its website. All working sources pass the live check (scripts/live-check-plugin.js) with 4/4 steps.

1. Chireads (plugins/french/chireads.ts) — rewritten for the new site theme

The site was redesigned with a new "chireads-refresh" WordPress theme and the old selectors (.romans-content, .inform-product-*, .chapitre-table) no longer exist, which is why no chapters appeared.

• popularNovels: parses the new ul.refresh-card-grid li.refresh-card cards (categories /category/translatedtales + /category/original, or /tag/…, paginated via /page/N/).
• showLatestNovels: parses the homepage "Dernières mises à jour" table (.dernieres-tabel), deduplicated by novel.
• parseNovel: .refresh-detail-title (name), .refresh-detail-cover img (cover), .refresh-detail-summary-content (synopsis), .refresh-detail-meta (author/status) and .refresh-detail-chapter-list a for the full chapter list (release date extracted from the /YYYY/MM/DD/ segment of the chapter URL).
• parseChapter: keeps #content (still present on reading pages).
• searchNovels: uses the WordPress search /?s=… and parses the .news-list li results.
• Version bumped to 2.0.0.

Live checks: 57 novels, 34 search results, 22 chapters, ~17.9 kB chapter body.

2. Ligh Novel FR (plugins/multisrc/lightnovelwp/sources.json) — site moved

lightnovelfr.com now permanently redirects to novel-fr.net (same WordPress LightNovel theme, same structure), which is what caused the 500/Captcha (hostname changed). Updated sourceSite to https://novel-fr.net/ and bumped the generated plugin version with versionIncrements (recommended by the generator README when the site URL changes). All 4 live checks pass against the new domain (14 novels, 82 chapters).

3. MassNovel (plugins/multisrc/madara/sources.json) — site moved, source removed

massnovel.fr permanently 301-redirects to novelfrance.fr, which is no longer a Madara site (it is now a Next.js app with its own API). The dedicated plugin plugins/french/novelfrance.ts already targets novelfrance.fr and passes all live checks — it is the replacement for MassNovel. Closes #2062.

4. MTL Novel (FR) (plugins/multisrc/mtlnovel/sources.json) — network dead, source removed

The whole mtlnovels.com network (fr, www and all subdomains) no longer serves content: every page returns a JS-boot challenge ("Loading…" page that redirects with a signed token and requires a real browser), including the autosuggest search endpoint. A plugin cannot work against it, hence the "no results" symptoms. Removed the mtlnovel-fr entry. Note: the other variants (EN/ES/ID/PT/RU) point at the same dead network and are equally affected.

5. WorldNovel — kept

Left as-is in the Madara generator. The underlying site (world-novel.fr / victorian-novel-house.fr, now branded "Victorian Novel House × World Novel") is still alive, but it has been rewritten as a client-rendered Next.js app whose data lives in a Firebase backend protected by App Check, fronted by a Cloudflare challenge — so no scraper can currently read its chapters (see #1692, #2090). The source is intentionally kept in place in case a workaround or a public API appears. Its live check reports siteReachability INCONCLUSIVE (HTTP 403 Cloudflare), which never blocks a merge.

Verification

• node scripts/live-check-plugin.js plugins/french/chireads.ts → 4/4 PASS
• node scripts/live-check-plugin.js "plugins/french/LighNovelFR[lightnovelwp].ts" → 4/4 PASS (generated from the updated sources.json)
• node scripts/live-check-plugin.js "plugins/french/WorldNovel[madara].ts" → siteReachability INCONCLUSIVE (HTTP 403 Cloudflare, expected)
• npx eslint plugins/french/chireads.ts, npx tsc --project tsconfig.production.json --noEmit and prettier all pass.

Generated multisrc plugin files are gitignored.
