[eudelins-zama]

Closes https://github.com/zama-ai/fhevm-internal/issues/625

[Copilot]

Pull Request Overview

This PR introduces a comprehensive version management solution for the fhevm monorepo, including a Python script to automate version bumping across all sub-projects and a GitHub Actions workflow to enforce version consistency.

Summary: The PR adds a centralized versioning script (ci/versioning.py) that can check and update versions across multiple sub-projects (Rust and JavaScript/TypeScript) in the monorepo, bumping all versions to 0.10.0.

Key Changes:

• Added Python script for automated version management with check and update commands
• Introduced GitHub Actions workflow to validate version consistency on PRs and releases
• Updated versions across all sub-projects to 0.10.0
• Removed legacy git hooks (commit-msg, pre-push, and installation script)
• Standardized Rust edition to 2024 across workspace projects
