[Sync] Update project files from source repository (16d1713)

[mrz1836]

What Changed

• Deleted the monolithic .github/.env.base configuration file (550 lines)
• Created a modular environment configuration system with separate files in .github/env/:
  • 00-core.env - Core Go version and module configuration
  • 10-security.env - Security scanning tool configuration
  • 10-coverage.env - Code coverage settings
  • 10-mage-x.env - MAGE-X build tool configuration
  • 10-pre-commit.env - Pre-commit hook settings
  • 20-workflows.env - GitHub workflow configuration
  • 20-redis.env - Redis service configuration
  • README.md - Documentation for the new environment system
  • load-env.sh - Shell script for loading environment files
• Updated .github/actions/load-env/action.yml to use the new modular configuration loading system
• Added .github/actions/download-artifact-resilient/action.yml for resilient artifact downloads
• Updated multiple workflow files to reference the new environment configuration structure
• Updated documentation in .github/docs/repository-features.md and .github/docs/workflows.md
• Updated technical conventions documentation in .github/tech-conventions/
• Added .github/.yamlfmt configuration file
• Updated .github/CODEOWNERS file

Why It Was Necessary

• The monolithic 550-line .env.base file was difficult to maintain and navigate
• Splitting configuration into domain-specific files improves organization and makes it easier to find and modify specific settings
• The new modular approach allows workflows to load only the environment configurations they need, improving clarity and reducing overhead

Testing Performed

• Verified that all 32 modified files are consistent with the new modular environment configuration approach
• Confirmed that the new load-env.sh script properly handles loading multiple environment files
• Validated that workflow files correctly reference the new environment configuration locations
• Ensured documentation accurately reflects the new configuration structure

Impact / Risk

• Breaking Change: Projects using the old .env.base file directly will need to migrate to the new modular structure
• Risk: Medium - Configuration loading logic has changed, requiring thorough testing of all affected workflows
• Benefit: Improved maintainability and clarity of configuration management across all workflows and tools
