Shared tax tools for VS Code Copilot

Commit your MCP config to the repository so every engineer uses the same `calculate_cumulative_tax` logic. This keeps your entire team on the same page for tax reporting. It removes the need for individual setup while ensuring everyone has access to the same calculation tools.

Process non-cumulative taxes in VS Code

Use `calculate_non_cumulative_tax` to check your net liabilities during your daily dev cycle. The tools integrate into the chat to provide quick answers to your tax questions. This makes it easy to confirm your figures without leaving your IDE or opening external calculators.

Evaluate regimes across the team

Run `evaluate_regime_comparison` to help your team decide on the best tax structure for your current project. The results are visible to anyone using the shared configuration. This promotes consistency across your organization by giving everyone a reliable way to compare tax outcomes.
