Description

Fix webhook createWebhook and updateWebhook methods in the TS SDK that were sending camelCase keys (eventTypes) in the HTTP request body instead of snake_case (event_types). This caused
createWebhook to fail with a 400 error and updateWebhook to silently ignore event type changes.

Also adds integration test coverage for webhook CRUD operations and bumps the SDK to v2.4.2.

Type of change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

• Unit Test
• Test Script (please provide)

Unit tests (84 pass):
npx jest --testPathPattern="memoryClient" --no-coverage

Integration tests against real API (7 pass):
MEM0_API_KEY= npx jest --testPathPattern="integration/management" --no-coverage --forceExit

Manual verification — raw HTTP calls confirming:

• createWebhook with camelCase eventTypes → 400 error
• createWebhook with snake_case event_types → 201 Created
• updateWebhook with camelCase eventTypes → 200 but silently ignored
• updateWebhook with snake_case event_types → 200 and actually updated
