Major Changes

• #11308 c809e09 - feat: rewrite the adapter onto Solid 2.0's native async model. Query reads
  are now a single async computation (suspends into <Loading>, holds
  previous data through refetches, routes rejections to <Errored>,
  serializes settled values for streaming hydration) served through an
  auto-reconciling store projection — deep reads are fine-grained and item
  identity survives across fetches (keyed by the reconcile option, default
  'id'). Mutations ride Solid core's action primitive (transactional
  settle, optimistic overlays, callbacks inside the transaction). The
  observer notification/store layer is deleted —
  QueryObserver/MutationObserver remain as lifecycle/policy engines only.
  Hydration is single-channel and content-addressed (the Solid Router
  query() pattern): the provider serializes every query the request
  touches into Solid's hydration registry under sq:<queryHash> at
  fetch-dispatch time, each client hook primes the query cache from its own
  hash entry through query-core hydrate(), prefetched-never-rendered
  queries transfer, late mounts adopt past hydration end, and the
  provider-owned dehydration channel is deleted. Requires solid-js >=
  2.0.0-rc.4 (hydration-end divergence takeover).

  Breaking: data is non-optional on query results (reads suspend instead of
  returning undefined) and is a readonly store view; mutateAsync removed
  (mutate returns a promise); reconcile is now the reconciliation key for
  the data store (string | (item => any) | null, default 'id' — the v5
  function form is gone, core auto-reconciles); suspense option removed
  (suspension is the model, boundaries are the control point); the create*
  runtime and Create* type aliases are removed, completing the deprecation
  from #8950 — use* is the only naming; isInitialLoading (deprecated
  alias of isLoading) is removed from query results. deferStream is now implemented
  (it was declared but unwired on the v6 line): it passes through to Solid's
  per-computation deferStream memo option.
