Subject: [PATCH] Add session list refresh with server cache bypass

useSession now exposes a refreshSessions() callback that fetches
/api/sessions?refresh=1. The sessions route checks for the refresh
query parameter and resets the cache timestamp to zero, forcing a
fresh scan of ~/.claude/projects/ on the next request.

This enables users to pick up new sessions without restarting the
server or waiting for the 30-second cache to expire.
