docs/language: a page for every keyword and attribute the vocabulary has

Keywords: module uses friend export internal numbers unsafe mut port bind action
reducer registry of as from def open alias component prop view (structure),
shows lasts then loads (scenes), system (ecs), dispatch (control), true false

that is not marked skip parses (ludicc --fmt). annot-clearcolor's token loses its
quotes, which no reader strips.

+<code>numbers float</code> at the top of a file makes a bare decimal such as <code>1.5</code> a <code>float</code> rather than a <code>fixed</code>. Such a file also refuses to promote a computed <code>int</code> silently: write <code>float(n)</code> where a count becomes a number.
