Refine track number filename extraction — separator required

Browse source 
_extract_track_number_from_filename now requires a separator after
digits (dash, dot, bracket) to prevent parsing artist names like
"50 Cent" as track number 50. Also handles disc-track format "1-03".

This is a last-resort fallback only — standard downloads get track
numbers from Spotify/iTunes/Deezer metadata. Only affects files with
no metadata where the filename starts with digits.
