- Fix a stale test title that still claimed a delete button is visible.
- Strengthen the two "never renders a delete button" contract tests
(AnnotationShape + AnnotationLayer specs) to assert the annotation
element has zero descendant <button> elements, not just the absence of
the removed testid (a near-tautology now that the testid is gone).
- Harden the e2e delete test: guard countBefore > 0 so a missing seed
fails clearly instead of asserting toHaveCount(-1), and capture the
deleted annotation's testid to assert that specific element is gone
(identity check) alongside the count drop.
