chore: release Anvil 0.4.0, Lathe/Temper/Knurl 0.3.0, Planish/Braze/Ballast/Forge 0.2.0, Crucible/Weld 0.4.0

The producer-feedback round: stable note tracking, the NOTE pitch source with
Key lock and Follow bends, unsure-means-neutral fallbacks, Anvil's Enhance
mode, MAIN and ADVANCED pages, Ballast on Grid by default, and Crucible's
sure-note slice names with a song key.

Adds docs/pitch.md for the shared pitch source, updates every changed
plugin's README and changelog, the release table, the editor previews, the
website bullets, and the status in docs/ideas.md.

 # Temper changelog
 
+## 0.3.0
+
+- Add **NOTE** as a pitch source: Temper follows a note you set, and the audio
+  only starts and stops it. Add Key lock and Follow bends for AUDIO detection.
+- Detection holds its notes: a new note needs a steady pitch for 40 ms, octave
+  jumps need 80 ms down and 200 ms up. Growls, wobbles and formant basses no
+  longer flicker between notes. Follow bends brings back the old fast behaviour.
+- When detection is unsure, Temper keeps the tuning of the last sure note, and
+  the readout shows **?**.
+- The editor opens on a MAIN page. **ADVANCED** in the header adds Push at,
+  Floor, Bright, Normalize and Gate.
