adminandClaude Opus 5.5 f92d69d902 Rebuild the Acid node after the acid voice of nodeseq (#421) ...

The first Acid hardly squelched. Its tanh ate the resonance, and its
sweep fell evenly in octaves. The user pointed at the acid tone of
nodeseq.com/studio, so the node now follows how that voice is built
from Web Audio parts.

- The filter is a two-pole 12 dB low-pass with Q in dB up to 17.5,
  like a BiquadFilterNode. The ladder and its tanh are gone.
- One ADSR drives both the volume and the filter. The sweep falls
  back in Hz, fast from the top and long at the bottom.
- Every note glides from the one before. A new note cuts the last
  one off, and the node plays its release itself.
- Knobs: cutoff, reso, env, attack, decay, sustain, release and
  glide. The defaults are the acid preset of nodeseq.
- Accent, slide, drive and tuning are dropped. Old projects were not
  kept, the user had only placed the node for a try.
- A hook __gm.acid.compare renders a line offline through our
  worklet and through the nodeseq graph, for e2e 34.

Found on the way: in Chrome an oscillator that starts inside a
render block runs its first samples at 440 Hz. The comparison evens
this out.

Tests:
- tsc, eslint, Prettier clean
- Unit: acid.test.ts rewritten with 12 tests. chip-presets and
  sound-library follow the new node.
- e2e 34 on melektaus-atx: ALL PASSED, 148 checks. Against nodeseq
  the loudness per 10 ms window is at most 0.14 dB apart, and 95 to
  97 % of the windows are equally bright.
- With a linear Q instead of Q in dB the comparison is red.
- Gate on melektaus-atx: green, 306 files, 4752 tests. That is
  4754 less the 14 old and plus the 12 new Acid tests.
- Not checked: the sound by ear, the master chain of nodeseq, the
  keyboard and a bake with the new node.
