test(morfo): fix stale role-hoist assertion + guard the dialog-001 deliberate absence

The dialog-001 a11y-race fix (53b6f629) removed the literal role from dialog
Content on purpose — variant-dependent dialog/alertdialog, DialogContentProvider
is the sole authority — but the compile test kept asserting the static hoist on
that part, red on HEAD since then. Adjudicated: stale test, not a compiler
regression (mechanism verified intact via Title, which does declare a literal
role: heading).

- Re-point the hoist mechanism test at Title (heading).
- New guard: Content emits NO static role, locking dialog-001 against a
  re-declared literal reintroducing the syncAttrs overwrite race.

Suite 35/35 (was 33+1 failed); type baseline 57.
