nvrl 5cc3770737 feat(knurl): add Knurl cycle texture ...

Knurl follows the played note and treats every cycle of the wave on its
own: a repeating level pattern over 1-16 cycles makes subharmonics in tune
with every note, random level and timing per cycle add rattle, and a noise
burst per cycle, highpassed at a multiple of f0, adds grit. Amounts are
counted in cycles, so the texture is the same on F1 and on C2.

- Cycle clock from the shared note tracker, restarted at each note; the
  audio is delayed by the lookahead plus 4.2 ms of timing-jitter headroom.
- Per-cycle randomness from a hash of the cycle number: Same every note
  or Free.
- Patterns Off, Double, Triple, Fry (default), Gallop, Stutter or drawn;
  grit switchable per step. Pattern persisted as knurl-pattern.
- Editor: last eight cycles overlaid, pattern bars with the playing step.
- Tests match the prototype: Double gives f0/2 at -8.19 dB, Triple f0/3
  at -10.68 dB, equal on F1 and C2, no added clicks, bit-exact when off,
  no allocation on the audio thread.
