Initial implementation of video_probe (Rust)

Core modules:
- probe.rs: ffprobe execution logic
- parser.rs: JSON parsing logic
- output.rs: Output formatting
- lib.rs: Library interface
- main.rs: CLI entry point

Features:
- Extract video metadata using ffprobe
- Parse video/audio/subtitle streams
- Save to JSON file
- Console summary output

Documentation:
- Added QUICKSTART.md
- Added ENVIRONMENT_SETUP_REPORT.md
