feat: ship as npm package via @netresearch/agent-skill-coordinator

[CybotTM]

Summary

• Adds package.json so the skill is npm-installable straight from this GitHub repo (no npm-registry publication required to start).
• README gains a parallel npm (Node Projects) section under Installation, mirroring the existing Composer (PHP Projects) section.

How discovery works (consumer side)

npm install --save-dev \
  @netresearch/agent-skill-coordinator \
  github:netresearch/matrix-skill

After install, the coordinator's postinstall walks node_modules, finds this package via aiAgentSkill: skills/matrix-communication/SKILL.md, validates the frontmatter, and writes a <skills_system> block into the project's AGENTS.md. Same shape as the Composer plugin's output.

Why version stays at 0.0.0-source

Versioning still lives in git tags and the existing Composer release workflow. A real npm version would be set at publish time; until then, 0.0.0-source is the standard "this manifest exists for tooling, not as a release marker" placeholder.

Code Review

This pull request introduces npm support for the Matrix skill by adding installation instructions to the README and creating a package.json for distribution. Feedback indicates that the .claude-plugin/ directory should be included in the files array to ensure the manifest is packaged, and the aiAgentSkill field should be converted to an array to correctly register both the communication and administration skills.

Pull request overview

This PR adds npm-installation metadata for the Matrix skill repository so Node-based projects can consume it through @netresearch/agent-skill-coordinator, alongside the existing Composer-based distribution path. It extends the repo’s packaging/discovery story rather than changing the Matrix skill implementations themselves.

Changes:

• Add a root package.json that makes the repo installable as @netresearch/matrix-skill from GitHub.
• Declare npm-side skill discovery metadata and packaged file list for the coordinator workflow.
• Document the Node/npm installation path in README.md, including pnpm postinstall allowlisting.

Updated composer.json + package.json so aiAgentSkill is an array of both bundled skills (matrix-communication + matrix-administration). Single-string declaration was missing matrix-administration.
