Added contains-deref? predicate to adapter-dom.sx. When rendering a text
expression that contains (deref ...) inside an island scope, the adapter
now wraps it in (reactive-text (computed (fn () (eval-expr expr env)))).
This tracks signal dependencies through arbitrary expressions like
(str (deref celsius) "°C") and (+ (* (deref celsius) 1.8) 32).
Previously only bare (deref sig) was reactive. Now compound expressions
like string interpolation and arithmetic over signals update in real
time. The temperature converter preview in sx-tools is fully reactive:
clicking +5/-5 updates both °C and °F displays live.
