Pull Request Overview

This PR introduces an AbstractBench interface to improve type safety and refactors the Bench class to expose properties directly instead of through an internal opts object. This change addresses issue #53 by making the benchmark configuration immutable and improving the API design.

Key Changes:

• Introduced AbstractBench interface defining the public contract for the Bench class
• Refactored Bench class to expose configuration properties as readonly class members instead of through bench.opts.*
• Updated all test files to access properties directly (e.g., bench.time instead of bench.opts.time)
