Merge branch 'main' into agent/lambda/bb798d97

`AssigneePicker` reads `squadListOptions` and `assigneeFrequencyOptions`
from `@multica/core/workspace/queries`. Tests that render IssueDetail
or IssueActionsDropdown without those mocks throw at the picker's
useQuery call and cascade into unrelated assertion failures — this is
what was leaving the `@multica/views` test job red on the MUL-2157 PR.

Add the missing mocks. Add a regression test that clicks the Assignee
menu item and asserts the shared picker (search input + Members group)
takes over, so a future regression to the parallel-implementation bug
this PR fixes fails loudly instead of silently.
