style(forks): use TSDoc for the new test declaration comments

CLAUDE.md requires TSDoc for documentation and no non-TSDoc comments. The
vi.mock boundary note, the resolve helper, and the beforeEach mock-reset
rationale all document declarations, so doc tooling could not associate them.
In-body step comments are left as-is - they explain a flow, not a declaration.
