Agent plugin and skills

The ten entries above are the skill documents in the fdc3-plugin plugin: /.agents/fdc3-plugin/plugin.json declares them, and /.well-known/agent-skills/index.json lists each one with a SHA-256 digest of its SKILL.md.

Each skill is served from /.well-known/agent-skills/<slug>/SKILL.md, which is where the entry URLs point and the only prefix this host answers for non-browser clients. The identical bytes also sit under /.agents/fdc3-plugin/skills/<slug>/SKILL.md, the Agent Plugins installation layout.

Versions and descriptions are the npm registry text, verbatim, including the upstream truncation in fdc3-schema's description. Display names, tags, example queries and skill prose are authored for this demonstrator; each skill document says so in its provenance section.
