[Sync] Update project files from source repository (bfde11d)

[mrz1836]

What Changed

• Removed the monolithic .github/.env.base file (550 lines) containing all default configuration values
• Removed .github/.yamlfmt YAML formatting configuration file
• Removed .github/CODEOWNERS file for automatic code review assignment
• Deleted the load-env GitHub Action (action.yml) that loaded environment variables
• Deleted the download-artifact-resilient GitHub Action for artifact downloads with retry logic
• Removed workflow documentation in .github/docs/workflows.md and .github/docs/repository-features.md
• Deleted the .github/env/load-env.sh shell script for environment variable loading
• Removed modular environment configuration files: 00-core.env, 10-pre-commit.env, 10-coverage.env, 10-mage-x.env, 10-security.env, 20-workflows.env, 20-redis.env
• Removed .github/env/README.md documentation for the environment configuration system
• Deleted technical convention documents: commit-branch-conventions.md and pre-commit.md
• Removed all GitHub workflow files: auto-merge-on-approval.yml, codeql-analysis.yml, fortress-completion-tests.yml, fortress-coverage.yml, dependabot-auto-merge.yml, fortress-test-magex.yml, fortress-setup-config.yml, fortress-warm-cache.yml, fortress.yml, pull-request-management-fork.yml, pull-request-management.yml, scorecard.yml, stale-check.yml, sync-labels.yml

Why It Was Necessary

• Consolidates or removes the GoFortress CI/CD configuration infrastructure from the repository
• Eliminates the complex multi-file environment variable loading system and related tooling
• Removes GitHub Actions workflows for testing, security scanning, coverage, PR management, and automation

Testing Performed

• Verify the repository can operate without the removed .github configuration files
• Confirm no dependencies exist in remaining code that reference the deleted workflows or environment loading system
• Validate that any alternative CI/CD configuration is in place if continuous integration is still required

Impact / Risk

• Breaking Change: All GitHub Actions workflows are removed, disabling automated CI/CD processes (testing, coverage, security scanning, PR automation)
• High Risk: Projects depending on these workflows will lose automation until alternative solutions are implemented
• Migration Required: Teams must implement replacement CI/CD pipelines or restore necessary workflows if automation is needed
