Adds a scrolling right-side panel showing real-time agent work pulled
from the Gitea API. Auto-refreshes every 30 s. Displays PR opens,
PR merges, issue opens, and issue closes with relative timestamps and
colour-coded event types. Panel is collapsible; collapses to a narrow
vertical toggle button. Gitea base URL and repo slug are configurable
via URL params (?gitea=, ?repo=) or Vite env vars (VITE_GITEA_URL,
VITE_GITEA_REPO) with defaults pointing at the live Gitea instance.
