- New POST /api/projects/[id]/dev-server/ensure: checks if dev server is running,
queries last known config from fs_dev_servers, fires startDevServer +
probeDevServerReadiness in background, returns immediately
- Preview pane calls ensure on mount when anatomy is loaded but no server is running
- Distinguishes state='running' (show iframe) from state='starting' (show warming-up UI)
- WarmingUpState: indigo spinner, elapsed timer, 'View last deployed version' link if available
- ensureCalledRef prevents duplicate calls per mount
- The 5s anatomy poll handles the starting→running transition automatically
