[Sync] Update project files from source repository (ac305ad)

[mrz1836]

What Changed

• Removed docs directory from .dockerignore, allowing documentation files to be included in Docker builds
• Added new composite action .github/actions/upload-artifact-resilient/action.yml that provides resilient artifact uploads with step-level retry logic (3 attempts with escalating delays of 10s, 30s)
• Updated MAGE_X_VERSION from v1.12.1 to v1.12.2 in .github/env/10-mage-x.env
• Replaced direct actions/upload-artifact@v4 calls with the new upload-artifact-resilient composite action across 8 workflow files
• Added permissions: contents: read to multiple workflow jobs for explicit permission scoping
• Modified artifact upload configurations to use the resilient action with configurable retry logic, overwrite behavior, and compression settings

Why It Was Necessary

• Transient GitHub infrastructure failures (including non-retryable 403 errors from CDN/proxy intermediaries) were causing artifact upload failures in CI workflows
• The new composite action provides defense-in-depth with both step-level retries and internal retry mechanisms (ACTIONS_UPLOAD_RETRY_COUNT=3) to handle infrastructure issues
• Explicit permissions: contents: read declarations improve security posture by following the principle of least privilege for workflow jobs

Testing Performed

• Verified the composite action structure includes proper input validation, retry logic with escalating delays, and error handling
• Confirmed all 8 workflow files correctly reference the new composite action with appropriate parameters (artifact-name, artifact-path, retention-days)
• Validated that the action supports configurable continue-on-error behavior for critical vs non-critical artifacts

Impact / Risk

• Breaking Change: None - workflows maintain same external behavior while gaining resilience
• Risk: Low - the composite action wraps existing actions/upload-artifact@v4 with additional retry logic without changing core functionality
• Performance: Minimal impact under normal conditions; retries add 10-30 second delays only during transient failures
• CI Reliability: Significantly improved artifact upload success rate for workflows affected by intermittent GitHub infrastructure issues
