Chord.Parse reads "Cm7#5", "Cm#5" and "Cm+" as augmented chords with a major third (Cm7#5 comes back as Caug7) #340

What's wrong

In Chord.DetermineQuality (Semantics.Music/Chord.cs:360-376), both the aug/+ branch and the fifthAlteration > 0 branch return ChordQuality.Augmented without looking at IsMinor(body). Augmented always has a major third, so the spelled minor third is dropped.

Commit fecd433 (#335) fixed exactly this for the lowered fifth at :365-369 (IsMinor(body) ? Diminished : MajorFlatFive), but the raised-fifth branch right below it was not changed.

Failure scenario

Run against HEAD with a small console probe:

The parse succeeds and returns a different set of notes. m7#5 is a common lead-sheet symbol, so a chart containing it is silently voiced with E instead of Eb.

Suggested fix

Pick one:

• Represent it: add a minor-sharp-five quality, mirroring MajorFlatFive (third = 3, fifth = 8), and return it from both branches when IsMinor(body) is true. It should print back as Cm#5 / Cm7#5.
• Reject it: return false from TryParse for a minor third with a raised fifth, rather than returning a wrong chord.

Acceptance criteria

• Chord.Parse("Cm7#5") has tones [0,3,8,10] and round-trips, or TryParse returns false.
• The same holds for Cm#5, Cm+ and Cmaug7.
• C7#5, Caug and C+ are unchanged.
