Use published sci-brain-slides v0.1.0 package

[GiggleLiu]

Observation

The write-slides skill already targets sci-brain-slides v0.1.0, but its setup still requires cloning the release into a custom Typst package directory.

Issue

Version 0.1.0 is now published in the Typst registry. The manual checkout and package-path instructions are obsolete, and the gallery is not shipped in the registry archive.

Fix

Use typst init @preview/sci-brain-slides:0.1.0 and normal compilation. Link the layout guide, style tokens, and gallery at the upstream v0.1.0 tag. Explain how existing package-based decks can drop their checkout override, and align README.md and CLAUDE.md.

The package version and slide API remain unchanged. First use requires network access; later builds can reuse Typst's cache.

Verification

• Initialized a fresh deck with empty local-package and cache directories, downloading the published package.
• Compiled the documented starter command, inline API example, and all five themes at 22 pt without warnings, supplying the required DejaVu Sans font through TYPST_FONT_PATHS.
• Inspected a rendered starter slide and verified all three version-pinned documentation URLs.
• python3 scripts/validate_skills.py: 16 skills passed.
• uv run --with pytest --python /opt/homebrew/bin/python3 pytest -q: 273 passed. Used an isolated environment because the system Anaconda pytest launcher crashes while importing readline.
• Skill quick validation and git diff --check: passed.

Independent quality review

A fresh-context reviewer examined the complete diff and all three changed files against 18e4cdd.

• Design: no material findings; registry setup removes checkout management and keeps template ownership upstream.
• Documentation: README, CLAUDE.md, and skill setup, compilation, and migration instructions agree. Version-pinned upstream links resolve.
• Reproducibility: imports and initialization retain the explicit 0.1.0 pin.
• Tests: no tests changed. Author verified 273 passing tests, skill validation, clean-cache package initialization, and warning-free compilation of the example and five themes. Reviewer independently checked whitespace.
