New SX primitives for child-to-parent communication in the render tree: - spread type: make-spread, spread?, spread-attrs — child injects attrs onto parent element (class joins with space, style with semicolon) - collect!/collected/clear-collected! — render-time accumulation with dedup into named buckets ~cssx/tw is now a proper defcomp returning a spread value instead of a macro wrapping children. ~cssx/flush reads collected "cssx" rules and emits a single <style data-cssx> tag. All four render adapters (html, async, dom, aser) handle spread values. Both bootstraps (Python + JS) regenerated. Also fixes length→len in cssx.sx (length was never a registered primitive).
