refactor: migrate RNG and utility functions to common package

- Removed RNG interface and related utility classes from logic package.
- Added RNG interface and utility classes in common package.
- Implemented various RNG classes (ConstantRNG, MidpointRNG, SineRNG, SequenceRNG) in common package.
- Updated conversion utilities for BytesLike to ArrayBuffer and Uint8Array in common package.
- Adjusted tests to import RNG utilities from the new common package.
- Updated vitest configuration to resolve common package imports.
