Dynamic Skills & Agentic Demo Rediness

[braydonlowe]

As a developer, I want a dynamic skills registry so that I can add new tools without modifying core code.

Acceptance Criteria:

• Skills are auto-loaded from a /skills directory at startup
• Core tools ard xiliary tools are decoupled
• Only relevant toolsare exposed per ruleset
• System starts cleanly with missing or invalid skills

Sprint Tasks:

• Refactor server.js to implement skill loader
• Scan /skills directory on initialization
• Seperate manifold-core tools from auxiliary tools
• Implement tool filtering by installed rulesets
• Add basic validation/logging for skill loading.
