v0.2.0 - Schema Compatibility and Extraction Tooling

Highlights

Added --json-only to extract restored MCB content and existing JSON files while ignoring other file types.
Added full-task progress reporting with processing speed.
Improved compatibility with schemas exported by LLClientSchemaExporter.
Added Python utilities for preparing test data, copying client schemas, and merging schema exports.

Read the Minecraft version from LLClientSchemaExporter export-report.json.
Resolve LL client schema references when title-based $id values differ from underscore-based physical filenames.
Show real schema file paths in missing-reference errors.
Support schema roots without exist.json, contents.json, or a metadata directory.
Improved schema discovery, document mappings, beta format-version handling, and JSON document restoration.
Added semantic schema merging with reference rewriting and validation.

Added --json-only.
Added processing speed to the current and total progress bars.
Suppressed the use --list for details hint when --list or --list-all is already active.
Added filtering and reporting improvements for failed files, empty directories, archive splitting, JSON formatting,
and in-place extraction.
Improved result classification and concise/listed output modes.

prepare_test_data: copies Minecraft packs and optionally downloads schemas.
copy_client_schemas: copies LLClientSchemaExporter output from LeviLauncher installations.
merge_schemas: combines schema trees with semantic replacement and reference validation.
Minecraft discovery now checks registered packages and common installation paths without recursively scanning entire
drives.

Expanded English and Chinese documentation for CLI usage, brarchive structure, and MCB binary layouts.
Renamed the local test tree to tests/ and the schema fixture directory to tests/schemas/.
Added regression coverage for LL schema references, JSON-only extraction, progress speed, schema metadata, and
helper tools.
