Phase 4 - Stream Health and Fallback: - StreamHealthChecker with partial GET validation of m3u8 content - Bitrate extraction from BANDWIDTH tags - Response time measurement for quality ranking - Fallback ordering: live first, fastest response time first - GET /streams now only returns health-verified streams Phase 5 - HLS Proxy Core: - GET /proxy?url= - m3u8 playlist fetch with full URI rewriting - GET /relay?url= - chunked segment relay (never buffers full segment) - m3u8 rewriter handles master, variant, and segment URIs - Base64url encoding for URL parameters - CORS middleware for browser playback - Range header forwarding for seeking support
