-Added `isLoadingMore` property and `loadingMore:change` events to collections and live queries, enabling UIs to display loading indicators when more data is being fetched via `syncMore`. Each live query maintains its own isolated loading state based on its subscriptions, preventing loading status "bleed" between independent queries that share the same source collections.
+Added comprehensive loading state tracking and configurable sync modes to collections and live queries:
+
+- Added `isLoadingSubset` property and `loadingSubset:change` events to all collections for tracking when data is being loaded
+- Added `syncMode` configuration option to collections:
+  - `'eager'` (default): Loads all data immediately during initial sync
+  - `'on-demand'`: Only loads data as requested via `loadSubset` calls
+- Added comprehensive status tracking to collection subscriptions with `status` property (`'ready'` | `'loadingSubset'`) and events (`status:change`, `status:ready`, `status:loadingSubset`, `unsubscribed`)
+- Live queries automatically reflect loading state from their source collection subscriptions, with each query maintaining isolated loading state to prevent status "bleed" between independent queries
+- Enhanced `setWindow` utility to return `Promise<void>` when loading is triggered, allowing callers to await data loading completion
+- Added `subscription` parameter to `loadSubset` handler for advanced sync implementations that need to track subscription lifecycle
