- eval.sx: Add defstyle, defkeyframes, defhandler special forms; add ho-for-each
- parser.sx: Add dict {...} literal parsing and quasiquote/unquote sugar
- primitives.sx: Add parse-datetime, split-ids, css, merge-styles primitives
- render.sx: Add StyleValue handling, SVG filter elements, definition forms in render, fix render-to-html to handle HTML tags directly
- bootstrap_js.py: Add StyleValue type, buildKeyframes, isEvery platform helper, new primitives (format-date, parse-datetime, split-ids, css, merge-styles), dict/quasiquote parser, expose render functions as primitives
- sx-ref.js: Regenerated — 132/132 tests passing
