feat(ultracode): floating run windows with tab connector lines + dedicated toggle

Auto-popping draggable window per active ultracode/Workflow run, connected by a
glowing line to its originating session tab (resolved via claudeSessionId ===
sessionUuid). Mirrors the live agent grid; auto-closes after a run finishes;
dismissals are remembered. Additional to the existing docked panel.

New "Ultracode Floating Windows" setting (default OFF), independent of the
"Ultracode Agents" panel toggle; either toggle starts the workflow-run watcher.

Also bumps version to 1.1.3 and brings CLAUDE.md up to date for the ultracode
subsystem.
