Subject: [PATCH] feat(schema): add lexicon registry to module manifest
 (FR-043)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add the top-level `lexicon` key (term -> {definition, optional category})
and its LexiconTermEntry $def, mirroring edge_types/roles. Modules declare
a concrete-term lexicon the EARS object-aware vague-response check (FR-042)
consumes; the engine carries no hardcoded noun list (ADR 0009). Optional —
existing manifests validate unchanged.
