Subject: [PATCH] feat: accept space, &, / as artist separators in metadata
 editor
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Space as fallback separator on save when no explicit separator present
  (Artist1 Artist2 → Artist1;Artist2)
- & and / added to explicit separator set everywhere
- navidromeArtist (download path) also handles /
