feat: implement comprehensive benchmark suite and CI regression check

[DanielEmmanuel1]

This PR implements a robust benchmark suite using Criterion.rs to monitor performance across core debugger operations.

Changes:

• Added specialized benchmarks for WASM loading, contract execution, argument parsing, and storage operations.
• Implemented state_management benchmarks for breakpoint and call stack overhead.
• Fixed a STATUS_STACK_BUFFER_OVERRUN issue during contract execution by optimizing environment management.
• Integrated critcmp into CI workflow for automated regression detection (10% threshold).
• Updated README with actual baseline performance results.

Closes #213
