check-vocabulary.py now extracts the keywords selfhost/parse*.ludic actually
dispatches on and requires the header's declaration/clause keywords to be a
subset (LUDIC_KW_RESERVED exempts documented-but-unimplemented scene/layer/on/
start, itself checked so an implemented reserved word must be promoted). Closes
the highlighted-but-unparsed loop against the real compiler; verified it catches
an injected bogus keyword.
Reconciled the drift it exposed across ludic_syntax.h, JetBrains, TextMate, and
emacs: dropped scene/layer/on/start (->RESERVED), the never-implemented
needs/uses/requires/ensures/invariant/effects clauses, and the retired
edge/export/pure prefixes; added enum/main. @annotations highlight generically.
Tooling-only (no seed change): test.sh 14/14, check-vocabulary + test-tools 28/0.
Phases 1-5 complete.
