* feat: add slug parameter to action-loader for programmatic identification
Add optional `slug` parameter to ActionLoaderHandle for easier identification via code or CSS. Update all loader.show() calls across the codebase to include descriptive slugs ('app-init', 'chat-rename', 'chat-delete', 'bulk-delete', 'chat-load', 'image-generation', 'legacy-loader'). Add data attributes (data-slug, data-loader-id, data-blocking) to toast content div. Expose slug via getter and make id private with getter.
