Minor Changes

• Add an internal shared live-query observer and migrate all five framework adapters to it (#1642)

  Introduces createLiveQueryObserver in @tanstack/db: given a resolved live-query collection (or null for a disabled query) it owns the subscription lifecycle every adapter used to re-implement — change and status subscriptions, a snapshot with stable identity per state revision for wholesale consumers, and delivery of the raw ChangeMessage[] for granular consumers. React, Vue, Svelte, Solid, and Angular's live-query hooks now materialize from the observer instead of their own hand-rolled subscription/status/snapshot machinery, keeping each adapter's native reactivity and each adapter's data-loading policy (wholesale adapters subscribe without initial state; granular adapters seed from it).

  The observer is an internal, unstable contract for TanStack DB's official adapters — it is exported so the adapter packages can consume it, but it is not a public extension point yet and its API may change in any release.

  The migration also fixes several live-query lifecycle defects: status-only transitions (error, cleaned-up) now reach mounted consumers; snapshot identity is stable across unsubscribe/resubscribe and stays fresh while detached; dispatch is FIFO and non-reentrant with subscriptions identified by record rather than callback; disposing during the synchronous initial replay no longer leaks the collection subscription; subscribing after dispose throws instead of registering a dead listener; Solid guards its async resource continuations against superseded collections; and constructing an observer no longer activates sync. Observers activate on their first committed subscription unless an adapter has already started a pre-created collection supplied directly or returned from a callback.

Patch Changes

• fix(db): republish ordered live queries on an order-only move (#1669)

  An orderBy live query that reordered its rows without changing any projected
  row value (an "order-only move") previously emitted nothing, so useLiveQuery
  kept rendering the stale order. The live-query collection now publishes an
  explicit layout-change notification when this happens, and the shared live-query
  observer snapshot exposes a layoutRevision that increments on any visible
  membership, ordering, or order-only-move change. All five framework adapters
  pick this up via their existing wholesale re-read.

• Add the unstable, internal createLiveQueryWindowController primitive for (#1675)
  forward pagination. It coordinates collection-scoped window leases, commits
  pages only after subset loads succeed, restores windows after failures and
  cleanup, and lets React's useLiveInfiniteQuery become a thin binding without
  changing its public API or resetting pages for structurally equal dependencies.
