* fix: resolve unnamed element refs matching multiple elements (#500)
When a page has one unnamed button among several named buttons,
clicking its ref fails with "matched N elements" because the
locator `getByRole('button')` matches all buttons on the page.
Normalize unnamed interactive elements to `name: ""` so the
selector becomes `getByRole('button', { name: "", exact: true })`
which matches only buttons with empty accessible names.
