Opt out of span disambiguation. The context-vector step that resolves

-- Opt out of span disambiguation. The context-vector step that resolves
-- ambiguously-typed spans (for example SSN vs. phone number) runs on every
-- filter by default. A lean, high-throughput policy that does not need it can
-- turn it off per policy through the existing CONFIGURE ANALYSIS passthrough.
-- Skipping it trades that disambiguation for lower per-document cost. Subject to
-- the global feature also being enabled. New in spec v1.2. Compiles to
-- span-disambiguation.json.
