nvrl 53bc26d14d feat(patina): Tone guard for bass lines ...

Patina detects the played note (30-500 Hz) and remembers, over about
4 s, how high each spectral bump is at a fixed frequency and relative
to the note. Bumps that follow the note (a boosted harmonic the patch
is built on) get less cut; bumps fixed in Hz (formants, room modes)
are cut as before. On a saw line F1-F2 with harmonic 6 boosted, the
cut on that harmonic drops from 5.78 dB to 0.44 dB at 100 %, while a
fixed formant at 1.5 kHz stays at 5.78 dB. One held note is cut as
normal, since the two cases cannot be told apart.

- New parameter tone-guard (0-100 %, default 0), appended at the end;
  0 % is the old behaviour and old settings load unchanged.
- New Bass line preset.
- Editor: Tone guard control, NOTE readout and a strip over the
  spectrum where cuts are held back.
- No added latency, no allocation on the audio thread; patina-core now
  depends on common-dsp.
