refactor: bundle the whole template suite under flat-artist/ + fix references

flat-artist is now the single container: all 16 template skills + the R&D
references/ moved inside flat-artist/. Cross-references updated — the orchestrator
points to bundled `<name>/SKILL.md`, sub-skills point to `../<name>/SKILL.md`,
and the R&D report path is relative. README catalog updated.

+description: A taxonomy of video template TYPES to build for FlatRender, with the purpose, key editable elements, suggested style/aspect, and 2D-vs-3D recommendation for each. Use when deciding what template to create next, planning a content batch, or scoping a requested template into a known pattern.

+
+# Template catalog — what to build
+
+FlatRender already has these (services/remotion `TEMPLATES`): IlluminatedCircles, KineticQuote, GradientPromo, VerticalStory, LogoMotion, Opener, InstaPromo, YouTubeIntro, Slideshow, HappyBirthday, SalePromo, QuoteCard, EventInvite, Countdown, GlitterReveal (editable logo), NowruzGreeting (2D characters), + 3D: Hero3D, Nowruz3D, Birthday3D, Promo3D.
+
+Use this map to pick the NEXT one and to scope a request into a pattern. Each row: key editable elements · suggested style · best aspect(s) · 2D/3D.
+

+
+## How to choose next
+1. Prefer **gaps** with high value for an Iran-facing product: Yalda, wedding, product showcase, testimonial, lower-thirds, outro/subscribe, music visualizer.
+2. Pick a STYLE that differs from neighbors (don't ship five dark-particle reveals) — see `../remotion-design-styles/SKILL.md`.
+3. Decide 2D vs 3D by subject (logos/products/abstract → 3D shines; text/character/illustrative → 2D or hybrid).
+4. Confirm a storyboard with the user for anything character- or scene-heavy.
+
+## Per-template build steps
+Storyboard (confirm) → build composition (lib helpers, design-styles, character-design) → make it fit all aspects (`../remotion-aspect-ratios/SKILL.md`) → wire editable text/logo/colors (`../remotion-template-composition/SKILL.md`, `../remotion-svg-colors/SKILL.md`) → pick fonts (`../persian-fonts/SKILL.md`) → optional music/SFX → render thumbnails + preview → seed (`scripts/seed_remotion_templates.py`) → deploy.
