Adds a reverse proxy to `wmill dev` that serves the Windmill UI on localhost, enabling Claude Desktop/Preview to open dev pages. Each connected dev page can watch a specific file via the `path` URL param and `setWatch` WebSocket message. Key changes: - CLI: single-port proxy (default :3100) that forwards HTTP to remote Windmill, handles /ws_dev locally for dev file changes, and proxies /ws/* to remote - CLI: per-client watch filtering so multiple tabs can watch different files - CLI: flow broadcasts now include a `path` field - Frontend: Dev.svelte connects to same-origin /ws_dev when no port param, sends setWatch on connect, filters messages client-side as safety net - CLI init: generates .claude/skills/dev-preview/SKILL.md and .claude/launch.json Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
