Refactor: Convert tests from broothie/test to testify (#16)

* Convert tests from broothie/test to testify

- Replace all instances of broothie/test with stretchr/testify
- Use assert.* for test assertions and require.* for must-pass conditions
- Update go.mod and go.sum to remove broothie/test dependency and add testify
- Maintain existing test logic and behavior

* Fix testify usage: use assert.* for most assertions, require.* only for Must functions

- Convert most require.NoError back to assert.NoError
- Keep require.NoError only for the original test.MustNoError call
- Maintain proper distinction between assertions and requirements
