* feat(core): audio FX registry One declarative description of every effect that can be applied to an audio track: fourteen across filters, dynamics, non-linear and time, each exposing its full parameter surface rather than a curated subset. Parameters carry the range, step, unit and scale a control needs, so a panel can generate its UI from this rather than hard-coding a form per effect, and a value that survives `normalizeAudioFxParams` is always safe to realise. Everything is declared in the units a person thinks in — dB, ms, Hz. Parsing rejects an unknown effect id rather than skipping the node. A chain that quietly loses an effect renders something other than what was authored, which is worse than refusing to load it. Data only: no audio is produced here. The graph that realises each effect is referenced by the `web` id and lands in the next change, which keeps this module free of browser globals so the engine and the linter can import it. * fix(core): stop declaring knobs that move nothing Three parameters were declared with ranges, defaults and hints, and read by no builder — dials an author could turn with no audible result. - `chorus.decay` and `bitcrush.aa`: removed. FFmpeg's chorus feeds a decay back into its delay line and a bitcrusher's anti-alias needs a real filter; adding either is new DSP, not a fix, so the honest move is to stop advertising them. - `lowshelf.q` / `highshelf.q`: removed. The Web Audio spec leaves Q unused for shelving filters, so the control moved nothing — and because the shared Q helper marks it automatable, an author could draw an envelope on it and hear nothing at all. `phaser.decay` and `gate.knee` stay: the first drives the sweep depth, and the second is now read by the gate's processor. A test asserts each of these directly, since the existing exposure invariant only checks that a flagged parameter reaches an AudioParam — a parameter the node then ignores passes it.
