Initial commit — scientific-viz skill

Claude Code skill for publication-quality scientific visualisations:
chart, architecture, flowchart, comparison, pipeline. Bundles matplotlib
publication defaults (300 DPI, serif font, colorblind palette), NADEZHDA
project palette, Mermaid conventions, and ready-to-use templates.

Contents:
- SKILL.md                              — behaviour spec (5 types, generation pipeline)
- README.md                             — human-facing entry: when, install, examples
- reference/chart_patterns.md           — Pareto/bar/radar/heatmap snippets
- templates/architecture_nadezhda.md    — Mermaid templates for Teacher-Student / LUPI / fusion
