v1.19.0

Added

• Chronoflow: particle trails are now long-exposure light streaks. Phosphor, Flux, and Murmur trails flow along each particle's motion like a long-exposure photograph instead of ghosting in place, and on every beat a shutter snap collapses the streaks so the image goes momentarily crisp. Loudness stretches the exposure; new beat_snap and flow_stretch params (plus trail_exposure on Murmur) tune it live, and existing trail_decay values keep their meaning.
• Custom effects can read the particle velocity field. A .pfx pass may declare "inputs": ["@particles.velocity"] (with "velocity_field": true under particles) to sample the compute rasterizer's per-pixel particle velocity as input0(uv) — the primitive behind Chronoflow, available to any custom multi-pass effect.
