Fair to develop

[dmytrotkk]

This pull request introduces significant updates to the build, test, and release workflows, adds new Fair node CLI functionality, and refactors several CLI modules for clarity and maintainability. It also updates project instructions and configuration files to align with new standards and practices.

Workflow and Release Process Improvements:

• Updated the release workflow in .github/workflows/publish.yml to support building and publishing both skale and fair binaries, with improved asset naming, checksum generation, and use of newer GitHub Actions versions. The build matrix and steps have been streamlined and generalized for future extensibility. [1] [2] [3] [4]
• Changed the test workflow in .github/workflows/test.yml to use ruff for linting instead of flake8, and added steps to build and check both skale and fair binaries. This ensures consistent formatting and that both build types are tested. [1] [2]

CLI Enhancements and Refactoring:

• Added a new CLI module node_cli/cli/fair_boot.py with commands for Fair node boot phase operations, including info, init, register, signature, and update functionalities.
• Renamed and refactored node_cli/cli/validate.py to node_cli/cli/chain.py, replacing ABI validation commands with Fair chain record and check commands, and updating copyright years. [1] [2]
• Updated node_cli/cli/exit.py to use a safer text loading method, improved option formatting, and streamlined command definitions for better maintainability. [1] [2] [3] [4]

Configuration and Documentation Updates:

• Removed .flake8 configuration and updated .github/copilot-instructions.md to clarify coding standards, linting, and testing procedures. [1] [2]
• Updated the Dockerfile to simplify Python environment setup and ensure compatibility with new development dependencies.

Version and Submodule Updates:

• Bumped the CLI version to 3.2.0 in node_cli/cli/__init__.py.
• Updated the helper-scripts submodule to the latest commit.
