### SUMMARY Chart tools return two different error shapes — `ChartError` has an `error` field while `ChartGenerationError` uses `message`. Clients need to check different field names just to read the error message depending on which tool they called. This PR introduces `MCPBaseError` as a shared base class. Both `ChartError` and `ChartGenerationError` now inherit from it, so every chart error response includes both `error` and `message` fields (same value), plus consistent optional fields like `details` and `suggestions`. Existing code is fully backward compatible — no call sites were changed. ### BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF <!--- Skip this if not applicable --> ### TESTING INSTRUCTIONS <!--- Required!
