File-Level Changes

Change	Details	Files
Introduce OtakusTV ParsedAnimeHttpSource implementation for listing, searching, and fetching anime, episodes, and videos.	Implement popular, latest, and search requests/selectors reusing shared card parsing logic. Parse detailed anime metadata including title cleanup, thumbnail, description, genres, and status mapping from site-specific markup. Build episode list by filtering /ver/ links to match the current anime slug and converting episode suffixes (including decimals) into episode numbers. Resolve video streams using multiple host-specific extractor libraries and a universal fallback, dispatching based on embed URL patterns. Override unused ParsedAnimeHttpSource selectors/parsers with UnsupportedOperationException and add helper regex-based title/label cleaning.	src/es/otakustv/src/eu/kanade/tachiyomi/animeextension/es/otakustv/OtakusTV.kt
Add WebView-based server extractor to decode encrypted server embed URLs from OtakusTV watch pages.	Instantiate an Android WebView on the main thread with JavaScript and storage enabled, loading the watch page with forwarded headers. Periodically evaluate injected JavaScript that hex-decodes encrypt attributes from DOM elements into embed URLs, with retry and timeout logic. Synchronize the async WebView extraction using CountDownLatch and clean up the WebView after completion. Return a de-duplicated list of absolute embed URLs split from the JS result string.	src/es/otakustv/src/eu/kanade/tachiyomi/animeextension/es/otakustv/OtakusTvServerExtractor.kt
Configure Gradle module for the new OtakusTV extension and declare extractor dependencies.	Declare extension metadata (name, main class, version code) and apply the legacy extension plugin. Add implementation dependencies for all required host extractor libraries (StreamWish, Dood, Voe, Uqload, Mp4upload, MixDrop, Lulu, Universal).	src/es/otakustv/build.gradle

**issue (bug_risk):** Using `abs:href` with `setUrlWithoutDomain` can create malformed requests.

`setUrlWithoutDomain` is intended to store a relative path that later gets prefixed with `baseUrl`. Passing a fully qualified `abs:href` risks producing URLs like `https://www.otakustv.nethttps://www.otakustv.net/...`. Normalize to a path-only value (e.g. use `link.attr("href")` or strip scheme/host from `abs:href`) before calling `setUrlWithoutDomain`.

Code Review

This pull request introduces a new extension for OtakusTV, implementing anime and episode parsing along with a custom WebView-based server extractor to handle obfuscated video hoster URLs. The review feedback highlights a few key improvements: using encodedPath to robustly extract slugs without query parameters, simplifying the description selector using Jsoup's :not() pseudo-class, and adding a guard flag in the WebView client to prevent multiple concurrent polling loops when onPageFinished is triggered multiple times.
