message: "Switch case should not be empty"

description: |
  Empty switch cases are confusing and likely indicate incomplete
  code. Add handling or remove the case.

  ✅ FIX: Add case body or remove

  ```typescript
  switch (x) {
      case 1:
          handleOne();  // GOOD
          break;
  }
  ```

query: |
  (switch_statement
    body: (switch_body
      (switch_case
        consequence: (statement_block) @BLOCK)))
