Hongming Wang a363b56f25 feat(tenant): combined platform + canvas Docker image with reverse proxy ... Single-container tenant architecture: Go platform (:8080) + Canvas Node.js (:3000) in one Fly machine, with Go's NoRoute handler reverse- proxying non-API routes to the canvas. Browser only talks to :8080. Changes: platform/Dockerfile.tenant — multi-stage build (Go + Node + runtime). Bakes workspace-configs-templates/ + org-templates/ into the image. Build context: repo root. platform/entrypoint-tenant.sh — starts both processes, kills both if either exits. Fly health check on :8080 covers the Go binary; canvas health is implicit (proxy returns 502 if canvas is down). platform/internal/router/canvas_proxy.go — httputil.ReverseProxy that forwards unmatched routes to CANVAS_PROXY_URL (http://localhost:3000). Activated by NoRoute when CANVAS_PROXY_URL env is set. platform/internal/router/router.go — wire NoRoute → canvasProxy when CANVAS_PROXY_URL is present; no-op otherwise (local dev unchanged). platform/internal/middleware/securityheaders.go — relaxed CSP to allow Next.js inline scripts/styles/eval + WebSocket + data: URIs. The strict `default-src 'self'` was blocking all canvas rendering. canvas/src/lib/api.ts — changed `||` to `??` for NEXT_PUBLIC_PLATFORM_URL so empty string means "same-origin" (combined image) instead of falling back to localhost:8080. canvas/src/components/tabs/TerminalTab.tsx — same `??` fix for WS URL. Verified: tenant machine boots, canvas renders, 8 runtime templates + 4 org templates visible, API routes work through the same port.
