Comprehensive Test Suite for Calendar Service
This ensures no functionality is broken in the optimized version

`CalendarServiceTester` runs checks against calendar service behavior and reports the results. It verifies exported functions, event shapes, date handling, batch limits, error paths, and mock synchronization before producing a test report.

## Methods

| Method | Signature | Returns |
|---|---|---|
| `testExportedFunctions` | `testExportedFunctions()` | `boolean` |
| `testEventObjectStructure` | `testEventObjectStructure()` | `boolean` |
| `testDateHandling` | `testDateHandling()` | `boolean` |
| `testBatchSizeLimits` | `testBatchSizeLimits()` | `boolean` |
| `testErrorHandling` | `testErrorHandling()` | `boolean` |
| `testMockSync` | `testMockSync()` | `Promise<boolean>` |
| `generateReport` | `generateReport()` | `void` |
| `runAllTests` | `runAllTests()` | `Promise<void>` |

## When something fails

- `CalendarServiceTester` handles failure in 1 place: it turns it into a return value in all 1.

## Usage

```ts
import { CalendarServiceTester } from "./calendar/comprehensive-test";

async function verifyCalendarService() {
  const tester = new CalendarServiceTester();

  await tester.runAllTests();

  const exportsValid = tester.testExportedFunctions();
  const datesValid = tester.testDateHandling();

  if (!exportsValid || !datesValid) {
    throw new Error("Calendar service checks failed.");
  }
}

void verifyCalendarService();
```

## AI Coding Instructions

- Keep synchronous checks returning `boolean` and preserve the asynchronous `Promise<boolean>` contract for mock synchronization.
- Add new service checks through `runAllTests()` so they are included before `generateReport()` runs.
- Test date values with explicit timezone and boundary cases to avoid environment-dependent failures.
- Keep batch-limit tests aligned with the calendar service limits rather than duplicating unrelated limits.
