v2.0.0

This release introduces a new validation pool and a more powerful validation chain with support for inversion logic and proxy blocks. Validation coverage has been expanded with many new rules, including DNS checks, instance validation, and traversal of object and array values. Error handling is improved through custom error key mapping, validation annotations, and passing inversion context to error data. The overall codebase has also been refactored for better structure, naming, consistency, and semantic clarity.
