Purpose
Speed up video seek-index deserialization with batch validation and a single tuple construction, avoiding repeated per-entry Python processing.
Preserve the wire format, tuple API and validation rules. Decompression remains bounded by the existing entry limit; writer-side validation remains streaming.
Tests
Added regression coverage for validation parity and bounded decompression. Related video and LeRobot tests pass.
