Create backend-agnostic middleware for loading and exposing agent skills.
This middleware loads skills from configurable backend sources and injects skill metadata into the system prompt. It implements the progressive disclosure pattern: skill names and descriptions are shown in the prompt, but the agent reads full SKILL.md content only when needed.
