#environment setup with bypass_prevrandao propagation

[Dargon789]

Reviewer's Guide

This PR enhances the formatting command to properly exclude libraries during recursive runs, introduces a new bypass_prevrandao configuration option for networks, and refactors environment setup to propagate network settings (including the new flag) across EVM and CLI components. Workspace and test updates ensure defaults and dependencies align with these changes.
