Fix disc numbering consistency and false tracklist matches

Browse source 
executor: disc=1 now generates '1-01' prefix (same as disc=2 → '2-01'),
  so multi-disc albums have consistent D-TT scheme throughout.
  Single-disc tracks without disc tag stay as plain 'TT'.

hint_extractor: tracklist pattern 2 now requires '.' ')' or ':' as separator
  (not bare whitespace) — prevents false-positive matches like
  '2 x CD, Compilation, Remastered' being parsed as track 2.
