Capture a same-session force-reload hint (loaded renderable/message counts,
known count, truncation flag) BEFORE clearing the in-memory transcript, so the
authoritative reload requests a width that preserves what was loaded instead of
collapsing a long session to the default 30-message tail window mid-read.
Same-session force reloads render with preserveScroll. Resolves conflict with
the shipped #3306 carry-forward snapshot by keeping both (complementary).
Closes#3239.

Force same-session external refreshes to dismiss stale approval and clarification prompts immediately so completed state.db updates do not leave the composer blocked.
When API server runs append messages directly to state.db, reconcile WebUI sidecar sessions with those canonical rows across API responses, model-facing streaming context, and active browser refresh.
Add append-only state.db merge helpers, metadata-only counts for refresh polling, and regression coverage for API visibility, context incorporation, and frontend refresh behavior.
