brarchive-extractor v0.2.1

What's Changed

• Restore JSON format_version from the version stored in the MCB header.
• Continue using the selected schema version only for decoding and diagnostics.
• Recognize Camera Document as a root schema for minecraft:camera_entity.
• Add regression coverage for MCB and schema version mismatches.
• Update the English and Chinese MCB format documentation.

Known Limitation

Camera restoration still requires schema exporters to emit "type": "object" for empty marker components. Untyped
empty camera schemas will continue to report unsupported-schema.

Verification

• All 24 automated tests pass.
