This PR closes #27
Description
When Vite dev server builds or restarts within the sandbox, the UI formerly displayed a generic spinner with no insight into compilation progress or startup status. This PR introduces live progress reporting by parsing and streaming Vite stdout logs to the frontend using Server-Sent Events (SSE).
Key Changes
Vite Log Streaming API: Created an SSE handler at GET /api/vite-logs-stream that checks the active sandbox (E2B or Vercel), reads the last lines of /tmp/vite.log, runs heuristic log parsing (to detect starting, building, ready, or error stages), and streams JSON status messages.
Provider Alignment: Updated e2b-provider.ts to output stdout and stderr to /tmp/vite.log upon starting or restarting, matching the Vercel sandbox provider.
Live Progress Overlay: Added a React state listener in app/generation/page.tsx connected to the SSE stream, showing a premium, glassmorphic compile overlay over the preview iframe containing live log outputs whenever Vite is compiling or restarting.
