feat: Add streaming URL resolver, quality detection, and server normalization

New endpoints:
- GET /api/stream/resolve — Resolves actual m3u8/mp4 URLs from embed player URLs
  Follows chain: vidtube.site → megaplay API → m3u8 playlist
  Returns url, type, qualities, subtitles, skipData
- GET /api/stream/qualities — Parses M3U8 playlists for available quality options
  Returns sorted quality list with resolution, bandwidth, URLs

New extractors:
- streamResolver.extractor.js — Full stream resolution pipeline
  - resolveStreamUrl(): Resolves embed → actual video URL
  - parseM3u8Qualities(): Parses master playlists for qualities
  - normalizeServerName(): Maps VidPlay-1 → vidplay, HD-1 → hd
  - extractSubtitles(): Extracts subtitle tracks from API responses

Enhancements:
- streamInfo.extractor.js: Added session establishment before AJAX calls
- Server list now includes normalizedName field for each server
- Stream info now includes type (hls/mp4) and backup URL
- Server list includes typeLabel (SUB/HSUB/DUB)
- Session cookies properly maintained for AJAX stream endpoints

Architecture:
- Embed API domain mapping (vidtube.site → megaplay-1.buzz)
- M3U8 parser supports master and media playlists
- Subtitle extraction from multiple API response formats
- 36 total endpoints (was 34)
