🧹 Re-evaluate unused SidebarTab type task

[mbayue]

🎯 What: Evaluated a code health task suggesting the removal of an unused SidebarTab type import in src/components/viz/AISidebar.tsx.
💡 Why: After investigating the codebase, it was discovered that SidebarTab is actively and explicitly used to type the tabs array and TabNavigationProps. Removing the import would force the use of convoluted inline type inferences (like ReturnType<typeof useVizStore.getState>['sidebarTab']), completely undermining the readability and maintainability goals of a code health task. The original code with the explicit type import is the superior pattern.
✅ Verification: Verified via grep and eslint that the type is actively used and not flagged as an unused variable. Attempting to remove it introduced type check errors and degraded code quality. No changes were made to maintain code health.
✨ Result: The explicit, clean type declarations are preserved, averting a degradation in code readability.

Summary by cubic

Verified the SidebarTab type import in src/components/viz/AISidebar.tsx is used and should remain.
The task asked to remove it if unused; it types tabs and TabNavigationProps, and removing it would require noisy inline types.
