fix(tui): hide empty sessions from the /sessions picker

Zero-message sessions no longer appear in the picker. Covers three
cases: the currently-running session (its file exists but no prompt
has landed in it yet), sessions the user exited immediately after
/clear, and any stale empties that PruneEmptySessions hasn't swept
yet.

Resuming an empty session was always a no-op, so nothing is lost.
The '(empty)' fallback summary in formatSessionRowPlain stays as
defense in case MessageCount > 0 but FirstUserText is blank.
