A player-agnostic local caching proxy for streaming video. Caches only the byte ranges a player actually reads (not whole files), with an LRU size cap.

• VideoCacheServer — loopback HTTP proxy. Translates the player's Range requests into chunk-aligned upstream fetches, streaming chunk-by-chunk and stopping when the player disconnects (an open-ended request only fetches what is played). Coalesces concurrent fetches (one per chunk, one length probe per key). Auth header forwarding, open-ended ranges, HEAD, whole-file fallback. Diagnostics: low-frequency onCacheStatus (one HIT/MISS per clip) + opt-in high-frequency onLog (per request/chunk).
• CacheStore interface + RangeCacheStore (default file-backed): chunked range storage, per-entry LRU eviction, pin() to keep a playlist resident, persists across restarts.
• UpstreamClient interface + HttpClientUpstream (default dart:io): pluggable transport.
• streamingVideoCacheVersion constant.

Pure dart:io — iOS, Android, desktop (not web).
