useViewport re-syncs the snapshot on pageshow/visibilitychange/resize/orientationchange — iOS reported a stale width on backgrounded-tab restore, leaving isMobile=false so the sidebar rendered as a permanent column with no close affordance. flattenToMessage now inserts pasted-text chips verbatim instead of wrapping them in a triple-backtick fence.

Session 1:N Chat data model with backfill. Workspace switches to client-side
multi-tab pane management. Right-rail file browser with float-over viewer and
click-drag line selection replaces FileBrowserPane. Adds /compact streaming
summarizer (respects compact markers in context builder), force-send (cancels
in-flight, persists partial as 'cancelled', awaits cancellation completion via
deferred Promise + 5s timeout), message queue, stop generation, chat
auto-rename, session archive/unarchive with Closed Sessions section on repo
landing page. CHECK constraints on sessions.status, messages.role,
messages.status with KEEP IN SYNC comments tying to MESSAGE_ROLES /
MESSAGE_STATUSES const arrays. Deletes dead pane routes/hook and the
api.panes.* client block.
