data: update user corpus — normalize CRLF, fix transcription errors

CRLF → LF normalization per .gitattributes for 24 files covering
celestial_sphere, clear_sky, looking_at_the_sky, mysterious_planet,
neon_day_beat, pastoral, reindeer_team, sparkle, summer_rain, toki,
wake_up.

Fixes:
  - reindeer_team-chorus: H7 → B7 (German/Russian H = B natural)
  - toki-verse: Fmsus2 → Fsus2 (sus chords have no 3rd)
