- Centralized common formatting, DOM, and status utilities in `includes/plugins/sdk.js`
- Created `sdk.utils.format`, `sdk.utils.dom`, and `sdk.utils.status` namespaces
- Refactored `domain.consensus` and `peer.visualize` plugins to use the global SDK
- Updated `plugin-handler` to serve SDK utilities globally via `/sdk-utils.js`
- Enhanced SDK validation by delegating to the core validation infrastructure
- Fixed bugs in metric rendering and missing frontend utility functions
