### Super high level description: Adds a nested/threaded view for Discourse topics, allowing posts to be displayed as an indented reply tree instead of the default flat chronological stream. Backend: - New /n/:slug/:topic_id routes serving roots, children (paginated), and context (ancestor chain) endpoints - TreeLoader recursively fetches reply trees with configurable max depth, Sort supports top/new/old ordering - NestedViewPostStat caches per-post reply counts (direct + total descendants, whisper-aware) with a backfill job for existing data - NestedTopic model tracks per-topic opt-in and pinned post Frontend: - Recursive <NestedPost> / <NestedPostChildren> components with lazy-load expansion, cloaking, and scroll tracking - NestedViewCache service preserves expansion state and scroll position across back/forward navigation (15 entries, 10min TTL) - Context view for deep-linking to a specific post with its ancestor chain - Floating actions bar, sort selector, real-time MessageBus updates Site settings (hidden): nested_replies_enabled, nested_replies_default, nested_replies_default_sort, nested_replies_max_depth, nested_replies_cap_nesting_depth, nested_replies_toggle_mode_groups, plus a per-category default override.
