ludic syntax, and ludic-dev syntax: every grammar written from the compiler's vocabulary and checked against it

`ludic syntax [--json] [-o FILE]` prints what `ludicc --emit-syntax` does (a line
per entry, or the JSON). `ludic-dev syntax` writes, between "ludic-dev syntax:
begin" / "end" lines, the keyword, type, phase and attribute tables of
ludic_syntax.h, LudicVocabulary's sets (JetBrains), ludic-mode.el's lists and the
language server's word tests (is_keyword_word and the rest; is_contextual_word is
every word the parser does not reserve, and every declaring or modifying one),
and every TextMate pattern marked "comment": "ludic-dev syntax: <group>" (shared
and the VS Code copy). The grammars gain module uses port bind action reducer
dispatch registry def open component prop view alias friend unsafe numbers of as
from mut system; import and extern colour as declarations; the phase clause
knows Overlay; the bitwise pattern matches | and ^ on their own again.

`ludic-dev syntax --check` - and check-vocabulary, whose old parser comparison it
replaces, and the regression suite (syntax_cases, one line per file) - fails when
a written list is behind, when a grammar lacks a keyword, type or phase, when
docs/language has no page for a keyword, type, phase or attribute, or when the
parser (a scan of selfhost/frontend: is_id / text == words, a == / ann ==
attributes) tests a word or reads an attribute vocab.ludic lacks, or the reverse.
