Subject: [PATCH] feat: add Bun polyfills and refactor LiteMCP implementation

- Introduced polyfills for Node.js compatibility in Bun runtime
- Moved LiteMCP implementation to a dedicated module
- Updated package.json to include @digital-alchemy/hass dependency
- Refactored import for LiteMCP to use local module path
