v0.4.0 - Deep Expansion

v0.4.0 — Deep Expansion

5 new dynamical systems (11 total now):

• Duffing Oscillator — forced nonlinear chaos, period-doubling route. Rhythmic, clicking, pulsing.
• Van der Pol — relaxation oscillator with tunable nonlinearity. Breathing, pulsing limit cycle.
• Halvorsen — complex 3D spiral. Dense, layered, evolving.
• Aizawa — toroidal attractor. Smooth, orbital, like the torus but stranger.
• Chua's Circuit — electronic double-scroll. Raw, gritty, harmonic buzz.

New synthesis engines:

• Karplus-Strong plucked strings — triggered by attractor crossings. Chaos becomes rhythm. Enable in Effects > Plucked Strings.
• Chorus/flanger — 3-voice LFO chorus. Makes everything instantly lush.
• Waveshaper — tanh soft saturation with drive. Adds warmth and grit.

Visual depth:

• Glow trails — two-pass rendering with bloom effect on phase portrait
• 3D rotation — Y-axis perspective rotation with auto-rotate on phase portrait
• Preset colors — each preset card has its own characteristic color

New presets: Duffing Rhythm, Chua Grit, Halvorsen Spiral
