* fix(sync): commit first message page before expansion loop (#2084)
loadMessages committed the store only after the full expansion sequence
(50→100→150), so the hydrating skeleton stayed for 3 sequential HTTP
round-trips when a session tail had no user message boundary.
Move the store write (materialize + setState) to happen after the first
fetch. The expansion loop now commits each expanded page incrementally
instead of overwriting a page variable and committing once at the end.
The first commit is gated on hasUserMessage(page.session) || page.complete:
if the tail is assistant-only, deferring to the expansion loop keeps the
skeleton (loading state) instead of rendering an empty chat that looks
like a fresh session. Sessions with a user boundary in the first 50
messages get content after a single round-trip.
* fix(sync): address review nits for #2084
- deferred init uses page.session instead of [] so limit reflects the
real fetched count if the expansion loop is ever a no-op
- both stale branches in commitMessagesToStore return messages: [] for
consistency
- add isStale guard between expansion fetch and commit for defense-in-depth
* fix(sync): always commit prepend-mode pages to store (#2084)
The deferred init path (assistant-only tail) skipped commitMessagesToStore
entirely when options.before was set — prepend mode. The fetched older
messages were never written to the store, silently dropping them.
Gate the deferral on !options.before: prepend mode always commits because
messages are already rendered (no skeleton to protect) and skipping the
store write would lose the fetched page.
