* fix: use direct assignee field
* fix: correct assignee trigger test to handle different assignee properly
The test was failing because the mockIssueAssignedContext was missing the
top-level assignee field that the trigger validation logic checks. Added
the missing assignee field to the mock context and updated the test to
properly override both the top-level assignee and issue.assignee fields
when testing assignment to a different user.
