docs: tidy CHANGELOG (drop duplicated [0.9] block) + refresh README

- CHANGELOG: remove the accidentally duplicated Changed/Fixed/Investigated
  block that sat orphaned before [0.8]; [0.9] now appears once.
- README: artist-pages bullet now mentions the same-name artist pin
  (Deezer link/id) and that a pinned artist's similar list comes from Deezer.

-- **Backend** — Japanese tracks now stored with original Japanese names in folders, filenames, and all main tags (title/artist/album/album\_artist); Romaji goes only into sort tags (TITLESORT / ARTISTSORT / ALBUMARTISTSORT / ALBUMSORT) for sorting and search in Navidrome. Previously, romaji was applied to filenames and tags too, causing name drift, duplicate misses, and wrong iTunes resolutions (e.g. "Hisaishi Yuzuru" instead of "Joe Hisaishi")
-- **Backend** — Metadata editor: files and album/artist folders are renamed using the original name typed in the form (may be Japanese), not romaji; sort tags still receive the romaji conversion
-- **Backend** — `album_artist` tag in downloaded tracks now consistently uses `mainArtist` (the iTunes-resolved album artist) rather than the raw per-track artist. This prevents Navidrome from splitting one album into multiple when track artists vary (e.g. compilations)
-- **Backend (download)** — No-duration cascade now ends after step 4 (same Mittelweg philosophy as the with-duration branch): no title-only or filter-free fallback grabs that pull wrong covers (observed: Yorushika 車窓 → Piano Echoes Shasou)
-- **Backend (download)** — `--max-filesize 30M` added to all yt-dlp calls; Mittelweg/no-duration steps also cap at 2× expected duration — a 28-min video can no longer be saved as a ~52 MB mp3

-### Fixed
-- **Backend (download)** — Duplicate detection now matches case-insensitively (DJ OKAWARI vs DJ Okawari) and across all album folders under the artist folder, comparing normalized title without track prefix or release/variant suffix — prevents re-downloading songs whose filename drifted between runs
-- **Backend (download)** — iTunes `collectionArtistName` (album artist) is now captured and passed through the download pipeline as the `album_artist` tag; fixes compilation albums showing "Various Artists" for some tracks and the individual track artist for others
-- **Metadata editor (autofill)** — iTunes button now fills all available fields: title (`trackName`), artist (`artistName`), album-artist (`collectionArtistName`), album, genre, year, track #, disc #, total tracks, cover
-- **Metadata editor (autofill)** — MusicBrainz button now fills album-artist (from release artist-credit) and disc # in addition to the existing fields

-### Investigated (Point 4 — album splitting)
-Primary causes identified:
-1. Missing `album_artist` tag / inconsistent value across tracks — fixed above (mainArtist + collectionArtistName)
-2. `tagAlbumArtist` was using `rawArtist` (per-track Spotify name) instead of `mainArtist` — fixed
-3. Album name comes from iTunes `collectionName` — consistent within a collection, no fix needed
-4. Year from iTunes `releaseDate` — album-level date, consistent within a collection
-5. MBIDs not set — still missing; not the primary splitting cause
