Latitude CLI v7.4.0

Added

• latitude sessions commands for reading sessions (the traces of one conversation, grouped by session id): list (cursor-paginated, with filters + free-text query), analytics (per-metric totals/medians and a 12-hour bucket series over whole sessions), get (session detail with its GenAI conversation and latest trace id), list-traces (cursor-paginated traces of the session), list-signals (signals recorded across the session's traces), and get-signal (one session-scoped signal by slug).
