Add FilmVault (filmvault.xyz) — Movies / TV / Anime / Korean Drama

FilmVault is a curated index and direct-download hub focused on Movies, TV shows,
Anime and Korean Drama. This entry includes the main site link and a short
feature summary to help users quickly decide if it fits the FMHY collection.

Why add FilmVault:
- Broad catalog: movies, TV series, anime and K-drama well-organized by genre and year.
- Direct-download-first approach with clear episode and file metadata (size, resolution).
- Regularly updated mirrors and verified download links to reduce link rot.
- Moderation and takedown responsiveness: site admin responds to reports and keeps mirrors updated.
- Low risk to users: lightweight landing pages, minimal intrusive pop-ups, and clear navigation that reduces accidental ad clicks.

This commit adds the one-line markdown entry used across other FMHY listings.
