Apex mocks

Allows verification of method calls with specific arguments and counts, throwing detailed exceptions on mismatches, as shown in the README's verify() example with clear error messages.

Enables stubbing method returns and exceptions using when() and thenReturn(), creating controlled test environments without external dependencies, demonstrated in the stubbing examples.

Leverages Salesforce's native Stub API to generate dynamic mock objects at runtime, ensuring seamless compatibility with the Lightning Platform, as highlighted in the documentation.

Provides utilities like fflib_ApexMocksUtils.setReadOnlyFields() to mock read-only SObject fields such as formula fields, which is unique to Salesforce testing needs.
