…sh workspace UI

Populate the thread list in the sidebar when navigating directly to a chat
detail URL so the workspace feels cohesive without an extra round-trip.
Relocate the mobile back button into _detail.html, add a New-chat shortcut
to the filter bar, improve thread-row layout with line-clamp title and
short_timesince, and fix chat-shell CSS grid to support a sticky header row.
