chore(fixtures): delete stale SafeDOMExample.res ReScript fixture (Re… (#30)

…fs gitbot-fleet#148, #208; affinescript#229)

Removes 1 copies of the stale SafeDOMExample.res ReScript fixture from
this repo. One of 1,267 byte-clustered copies across the estate (129
repos). ReScript is fully banned in new code (2026-04-30 policy
refresh). Current-grammar AffineScript replacement lives at
gitbot-fleet/bots/*/examples/SafeDOMExample.affine (PR gitbot-fleet#210
MERGED). The example fixtures are not load-bearing — propagated from an
earlier template-instantiation script.
