fix(ultracode): floating windows pop for LIVE runs (watch transcript tree)

The Workflow runtime writes workflows/wf_<id>.json only at completion (always
terminal), so workflow-run-watcher never saw a run until it was already done and
the ACTIVE-gated floating window never popped. The watcher now also scans
subagents/workflows/wf_<id>/ and synthesizes a minimal running record (agentId
slots preserved for the transcript-click join, lastActivityAt from mtimes,
done/running from the journal), superseded by the real wf_<id>.json at
completion. Standalone (no subagent-watcher import). Verified e2e on a real
in-flight run; +6 unit tests. Bumps 1.1.3 -> 1.1.4.
