feat(workers): Add dual-transport preflight system
Workers now run both curl and http (Puppeteer) preflights on startup: - curl-preflight.ts: Tests axios + proxy via httpbin.org - puppeteer-preflight.ts: Tests browser + StealthPlugin via fingerprint.com (with amiunique.org fallback) - Migration 084: Adds preflight columns to worker_registry and method column to worker_tasks - Workers report preflight status, IP, fingerprint, and response time - Tasks can require specific transport method (curl/http) - Dashboard shows Transport column with preflight status badges 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
