Implement "Commits Only" mode entirely on the client side to avoid data bloat, leveraging Store caching and App Worker performance.

GridContainer.mjs

• Modify afterSetCommitsOnly:
  • Swap the dataField of the Total column between totalContributions and totalCommits instead of overwriting renderers.
  • This leverages the Store's "Soft Hydration" (via doSort) to cache totalCommits values on the raw objects upon first access.
  • Propagate commitsOnly state to this.footerToolbar.

StatusToolbar.mjs

• Add commitsOnly_ reactive config.
• Update updateRowsLabels to compute the "Total Contributions" sum based on the active mode:
  • Default: Sum tc (Total Contributions).
  • Commits Only: Sum cy (Commits Year Array) using reduce.

This ensures zero data payload increase while maintaining high runtime performance.
