v0.4.0 — Production type configs, multi-scene sequencing, scene variety scoring

ProductionTypeConfig system — every production type (Mega-Demo, 64KB/4KB Intro, MusicDisk, Cracktro, Slide Show) now has typed config defining max effects, size budgets, per-category score bonuses, and suggested effort splits
Multi-scene sequencing — scene count selector (1–6) with per-scene effect assignment, 7 transition types (cut, fade, crossfade, slide, zoom, dissolve), and a SceneTimeline in the summary modal
Scene variety scoring — bonuses for scene count, unique transitions, and effect distribution across scenes
Production type scoring modifiers — each type biases scoring categories (4KB boosts originality; MusicDisk boosts music; Cracktro boosts audience appeal; etc.)
4 new rival groups — Crest (France), Spaceballs (Sweden), Triton (Germany), Complex (Finland) — plus 7 new sceners (Gibson, Zardax, Prowizard, Crypton, Membrane, Sync, Pixie)
Enhanced DemoStudio — type info banner with size budget tracking (color-coded at 50%/80%), multi-scene scene editor cards with transition dropdowns
Enhanced DemoSummary — SceneTimeline, production type config section, two new factor tiles (Scene Variety, Type Modifier)
