`SessionManager::create_saved_session_with_id_and_mode` picks the
first `ContentBlock::Text` off the user's message via `find_map`
and uses that as the session title. The engine prepends a synthetic
`<turn_meta>...</turn_meta>` block (Block 0) ahead of the real user
text (Block 1), so the `/sessions` picker was rendering the metadata
blob as the session name.
Guard the find_map filter on `!text.starts_with("<turn_meta>")` so
titles fall through to the actual user input. Existing sessions
without the prefix block are unaffected (the guard is a no-op when
no metadata block is present); the existing `truncate_title` long-
input handling continues to apply.
