Implements the collection pattern similar to area_registry as suggested in review feedback. This provides better performance and cleaner code organization. Changes: - Create ws-labs.ts with subscribeLabFeatures collection - Convert HaConfigLabs to use SubscribeMixin - Remove manual subscription and disconnectedCallback - Automatic updates via labs_updated event through collection - Separate translation loading from feature loading Benefits: - Automatic state management via collection - Debounced updates (500ms) to prevent excessive re-renders - Consistent pattern with other registries - Cleaner lifecycle management 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>
The ha-md-dialog style block with only --dialog-content-padding was redundant since we control padding directly in the .summary element. Changes: - Remove ha-md-dialog CSS block - Update .summary padding from (var(--ha-space-4) 0) to var(--ha-space-6) - This provides consistent spacing without the unnecessary override 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Use memoizeOne to ensure features are re-sorted when translations change (e.g., language switch), while avoiding unnecessary re-sorting on every render when dependencies haven't changed. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

Proposed change
This PR introduces Home Assistant Labs.
A feature that allows integrations to expose preview features that an user can opt-in to.
It provides a standardized way to ship preview features that users can opt into before they become standard / generally available. Labs preview features are critical bug free, fully functional features that are being refined through real-world usage and feedback before becoming standard in Home Assistant. They differ from beta testing, which evaluates release stability.
They differ from betas. A beta test, tests for general stability of Home Assistant, while these previews are aimed at validating and iterating new features that might not have yet reached the envisioned feature set.
