Fix hold() inflating Part.total_beats and Score.duration_ms — v0.40.8

Note.beats now returns 0.0 for held notes (_hold=True), matching the
renderer which already skipped advancing the beat position. Previously
every hold() call added its full duration to the part's total, causing
duration reports to be 2-3x too long on tracks with drone notes.

 All notable changes to PyTheory are documented here.
 
+## 0.40.8
+
+- **Fix hold() inflating duration** — `Note.beats` was returning the full
+  duration for held notes (`_hold=True`), causing `Part.total_beats` and
+  `Score.duration_ms` to overcount. A part with `hold(Sa, WHOLE * 4)` followed
+  by `add(Pa, QUARTER)` would report 17 beats instead of 1. Now held notes
+  return 0 beats, matching the renderer which already skipped advancing the
+  timeline for held notes.
+
+## 0.40.7
+
+- **Expose missing Synth enum entries** — rhodes, wurlitzer, vibraphone,
+  pipe organ, and choir wave functions were already implemented but not
+  accessible via the Synth enum. Now available as `Synth.RHODES`,
+  `Synth.WURLITZER`, `Synth.VIBRAPHONE`, `Synth.PIPE_ORGAN`, `Synth.CHOIR`.
+
 ## 0.40.6
 
 - **Saxophone presets cleaned up** — removed lowpass filters and vel_to_filter
