[Feature] - https://agent-plugins.org/ support agent plugins spec

[michaelBenin]

Area

Agent core, AI providers and models, Coding agent and CLI

Problem

Ability to install plugins that work for other harnesses and apply a standard.

Proposed direction

Support https://agent-plugins.org/

Alternatives considered

Manually setting up.

Additional context

I have plugins that work in copilot cli, claude, codex, etc would be great if I could test them out in prime. If it's supported we should add it to the list on this spec. After searching in the documentation I saw skills were supported but it wasn't clear if the plugins are.
