Version 0.13.0

• Versioned platform architecture & upgrades: Introduced version-aware parser registry that selects list or string parsers per platform version and defaults to the latest registered release. Auto-discovery for parser, serializer, and translator implementations. Added an upgrade pipeline that routes through the generic query as an intermediate representation, exposed through a new upgrade CLI subcommand.
• CLI improvements: Rebuilt the CLI around explicit translate, lint, and upgrade sub-commands with improved error handling and user feedback, including success messages emitted by the linter workflow.
• Search file handling: Refactored SearchFile to replace filepath with search_results_path, derive the default history path, ensure directories exist when saving, and exclude private attributes from serialization output.
• Linter updates: Added the deprecated-syntax warning (LINT_2001) to guide users toward upgrading queries that rely on legacy syntax.
• Documentation: Documented the syntax upgrade workflow and versioning policy for database-specific queries, including CLI examples.
