S-expression AST → HTML string renderer with ~100 HTML tags, void elements,
boolean attributes, XSS escaping, raw!, fragments, and components. Render-aware
special forms (if, when, cond, let, map, etc.) handle HTML tags in control flow
branches correctly by calling _render instead of _eval.
63 new tests (172 total across parser, evaluator, renderer).

S-expression parser, evaluator, and primitive registry in shared/sexp/.
109 unit tests covering parsing, evaluation, special forms, lambdas,
closures, components (defcomp), and 60+ pure builtins.
Test infrastructure: Dockerfile.unit (tier 1, fast) and
Dockerfile.integration (tier 2, ffmpeg). Dev watch mode auto-reruns
on file changes. Deploy gate blocks push on test failure.
