blastfx-v-0.2.0-beta1

First beta of the cinematic rework (0.2.0).

• Particle-driven fireball burst: equator-split hemisphere emitters feed the Mantaflow domain directly (replaces mesh inflow), with deterministic seeds and per-profile burst windows — fire now lingers scale-proportionally (~2 s small, ~3 s fuel, ~5 s large).
• Shading rebuilt per profile: density ColorRamp with near-black cores, Fresnel edge lightening, and the flame grid driving emission instead of the old temperature x400 hack.
• Physics in the expert-researched bands: vorticity capped at 0.2, profile-derived flame ignition, timeline-derived dissolve.
• Ground interaction: Mantaflow ground effector + particle collision, cool negative-temperature dust hugging the floor, and a keyframed expanding dust donut.
• Presets rebased (small/medium/large/large/heavy) with draft-quality resolution pre-scaling; Heavy Ground Burst long-burn preset added.
• Background bake queue, versioned dist zip, before/after example renders included (examples/before, examples/after).
