Proposal: make the repo a Claude Code plugin marketplace (2 small files)

[Adiakys]

Proposal

Add Claude Code plugin marketplace support so users can install Taste Skill directly from inside Claude Code with:

/plugin marketplace add Leonxlnx/taste-skill
/plugin install taste-skill@taste-skill

This is purely additive — npx skills add keeps working unchanged.

Why

Claude Code's plugin marketplace is a first-class install path for skills. Today users installing into Claude Code have to copy SKILL.md files manually or rely on npx skills add. Two small manifest files make the repo discoverable as a native Claude Code marketplace.

What changes

Minimal, additive:

1. New file .claude-plugin/marketplace.json — declares the marketplace and lists one plugin pointing at the repo root ("source": ".").
2. New file .claude-plugin/plugin.json — plugin manifest (name, version, author, repo, license, keywords).
3. Short note in README under "Installing" with the two slash commands.

That's it. No skill files move. The existing top-level skills/<name>/SKILL.md layout is auto-discovered by Claude Code when the plugin source is the repo root, so all 12 existing skills become available namespaced as taste-skill:<skill-name> (e.g. taste-skill:taste-skill, taste-skill:imagegen-frontend-web).

Compatibility

• npx skills add flow: unchanged.
• Existing users: no impact.
• Diff size: 2 new files (~30 lines of JSON), ~10 lines added to README.

Happy to send a PR

If this looks good, I can open a PR with the exact changes. Wanted to check interest first.
