Update Session
Rename a session.
session_title is denormalized onto every run in the session (the session
list reads the latest run), so a rename writes them all in one UPDATE. Null
clears the name and the UI falls back to the opening task — it does NOT
re-run title generation, which only fills rows where the title IS NULL and
so would silently overwrite the clear.

Lightweight metadata for one V4 session (its most recent run).
Deliberately slim — just what a session list needs (open the conversation, show a label + status + time). The heavy per-run fields (result, error, token/cost totals) live on RunSummary and aren't repeated here.
