Lock the hover content the dynamic-tooltip work produces. Ambience-level
cases (CSharpAmbienceTests) pin that SpecialType.Dynamic renders as
"dynamic" and that a synthetic dynamic method renders its return and
per-argument types - including the full hover form, confirming the
unnamed synthetic parameters collapse to their types with no dangling
name. An end-to-end case (HoverOnlyReferenceTests) decompiles a dynamic
call and renders the symbol GetSymbol hands back, exercising the actual
synthesis (argument typing from the callsite delegate), not a hand-built
stand-in.
