v2.0.1

Fixes

• Enharmonic map: Cbb, Fbb, bbC, bbF were off by one semitone (applied single flat instead of double flat)
• Interval table: #11 anglo_saxon label was d11 (diminished), corrected to A11 (augmented)
• Mode brightness: fix ranking to match circle-of-fifths ordering (Locrian=0, Phrygian=1, Aeolian=2, Dorian=3, Mixolydian=5, Ionian=6, Lydian=7)

Maintenance

• Updated all repository URLs after rename (gingo -> gingopy)
• Updated documentation links (MkDocs, README, pyproject.toml)
• PyPI package name remains gingo (unchanged)

All 496 C++ tests pass.
