Three issues with the eager kwarg evaluation in renderComponentDOM and
renderStrComponent:
1. Data arrays (e.g. tags list of dicts) were being passed to sxEval
which tried to call a dict as a function — causing blank pages.
Fix: only evaluate arrays with a Symbol head (actual expressions);
pass data arrays through as-is.
2. Expression arrays like (get t "src") inside map lambdas lost their
scope when deferred — causing "get,t,src" URLs. Fix: eagerly evaluate
these Symbol-headed expressions in the caller's env.
3. Bare symbol `t` used as boolean in editor.sx threw "Undefined symbol".
Fix: use `true` literal instead.

renderComponentDOM now eagerly renders kwarg values that are render
expressions (HTML tags, <>, ~components) into DOM nodes. But renderDOM
treated any non-array object as a dict and returned an empty fragment,
silently discarding pre-rendered content. Add a nodeType check to pass
DOM nodes through unchanged.

The string renderer's component call had the same deferred-evaluation
bug — and this is the path actually used for blog card rendering via
renderToString. Apply the same _isRenderExpr check to route render-only
forms through renderStr while data expressions go through sxEval.

The previous fix eagerly evaluated all kwarg expressions via sxEval,
which broke render-only forms (<>, raw!, HTML tags, ~components) that
only exist in the render pipeline. Now detect render expressions by
checking if the head symbol is an HTML/SVG tag, <>, raw!, or ~component,
and route those through renderDOM while data expressions still go
through sxEval for correct scope resolution.

renderComponentDOM was deferring evaluation of complex expressions
(arrays) passed as component kwargs, storing raw AST instead. When the
component body later used these values as attributes, the caller's env
(with lambda params like t, a) was no longer available, producing
stringified arrays like "get,t,src" as attribute values — which browsers
interpreted as relative URLs.
Evaluate all non-literal kwarg values eagerly in the caller's env,
matching the behavior of callComponent and the Python-side renderer.

Rename all sexp directories, files, identifiers, and references to sx.
artdag/ excluded (separate media processing DSL).
