fix: rewrite _createNdPlaylist to remove problematic Unicode regex

The normD regex used actual Unicode combining chars (U+0300-U+036F)
in the source which some build tools mangle, causing a SyntaxError at
runtime and silently killing playlist creation. Replaced with normA
that strips non-word/non-space chars via plain ASCII regex, which is
safe and achieves the same loose artist-first-word comparison.
Also fixed race condition in _pollAndCreatePlaylist — save lastStatus
before job is auto-deleted so the done check still works.
