Enhance test:all task to include integration tests

[coderabbitai]

Problem

Currently, the test:all task does not include integration tests from the test:integration task. This means that running "all tests" doesn't actually run all tests in the project.

Proposed Solution

• Modify the test:all task to include both unit tests and integration tests
• The test:all task should truly run all tests in the project
• Consider creating a separate task (e.g., test:unit) for running only unit tests if needed

Background

This enhancement was requested to ensure comprehensive test coverage when developers run the "all tests" command.
