Doobie v0.13.0

Added

• Full UI rebuild on JUCE 8's WebBrowserComponent — the entire editor
  is now an HTML/CSS/JS app served from BinaryData (no network), bridged to
  the audio engine via WebSliderRelay / WebToggleButtonRelay /
  WebComboBoxRelay + their matching *ParameterAttachments. All 96 APVTS
  parameters are two-way bound; host automation and preset loads flow
  through the same path as user drags. React + Babel-standalone vendored
  locally; the JUCE frontend JS is wrapped into a non-module IIFE that
  exposes window.Juce. CSP + WKWebView native scheme (juce://)
  configured correctly so the bundle loads fully offline.
• Gated reverb — new src/dsp/GatedReverb.{h}: plate core with an
  envelope-keyed sidechain gate. Classic 80s drum-gate sound — snare
  triggers a bright bloom that snaps to silence at the gate boundary.
  Surfaced as reverb mode #8 in the dropdown; three new APVTS params
  (gateThreshold, gateHold, gateRelease) appear as a row in the
  Reverb panel only when Gated is selected.
• Right-click knob context menu — Reset to default, Copy value, Paste
  value, Enter value… (the Enter-value path opens the styled modal). Per-
  knob via onContextMenu. The browser's native context menu is suppressed
  globally so the plugin reads as a native desktop app.
• Styled save-preset modal — replaces the JUCE AlertWindow that
  looked alien against the dark chrome. Cancel on Esc / scrim click; Enter
  to confirm; payload travels through the existing
  Juce.backend.emitEvent('preset_save', {name}) channel.
• Per-stage live VU bridge — engine now publishes inputLevel,
  delayLevel, reverbLevel atomics in addition to the per-channel
  outputLevel. The WebView's levels event ticks at 30 Hz with proper
  20·log10 dBFS values; the digital meters do their own RMS / peak-hold
  • clip indicator on top.
• Modulation indicators on every knob — any knob whose APVTS id is a
  matrix destination shows a dim outer arc + animated dot driven live by
  matrix amount × source depth. Includes the per-head pan/time
  destinations.
• Native-feel polish — selection / drag-select / right-click-Inspect
  suppressed via CSS + JS for everything except real <input> /
  <textarea> elements (so the preset-rename modal still accepts typing).
• Reverb route selector moved out of the top meter bridge into the
  Reverb panel itself, where it belongs.

Changed

• DecayGraph wired to the decay knob (was wired to size, which is
  unrelated to tail length — graph looked decorative).
• REC indicator removed from the cassette area (we're a tape echo, not
  a recorder; the light was misleading).

Fixed

• WebBrowserComponent use-after-free on close: the relays are
  WebViewLifetimeListeners whose destruction order had to come after
  the browser. Reordered class members.
• WKWebView showed "Could not connect to the server" because we navigated
  to https://doobie.localhost; JUCE only registers the juce:// scheme
  for served resources. Switched to getResourceProviderRoot().
• Two juce_add_binary_data targets (Voxengo IRs + UI assets) shared the
  BinaryData:: namespace, so the linker silently picked one and the UI
  resource lookup ran against the WAV file table. Each target now lives in
  its own namespace (DoobieIRData:: and DoobieUIData::).
• Vendored JUCE frontend JS still had an import at the top — illegal in
  a non-module script — so the IIFE never executed, window.Juce was
  undefined, and React threw on first render. The check-native-interop
  file is now inlined into the IIFE; verifier asserts no import/export
  survives the wrap.
• Hooks (useState, useEffect, etc.) were re-declared in multiple
  babel-script files → redeclaration SyntaxError. Hoisted to globals in
  the HTML shell so each .jsx can reference them directly.

Known issues (next iteration)

• Window scaling — the editor is 1520 × 960 native pixels and doesn't
  scale to fit smaller displays. Pending: CSS transform: scale() driven
  off the editor's actual bounds.
• Convolution-mode controls — irGain / irSpeed and the factory IR
  picker / "Load custom…" file dialog aren't surfaced; the Reverb panel
  shows the plate knobs even when the mode is Convolution.
• DecayGraph is approximated, not live. It draws an exp(-t/τ)
  envelope from the decay knob rather than the actual reverb impulse
  response. Live data would need an extra IR/RT60 emission from the
  engine.
• WKWebView inspection — patched the vendored JUCE source so
  developerExtrasEnabled is set in Release and setInspectable:YES is
  called on macOS 13.3+. Carry that patch forward when bumping JUCE.
