Function build_enum_case_body

src/hover/mod.rs:1657–1683

Build the body lines for an enum hover showing its cases. Only enum cases are shown (not regular class constants). Each case is rendered as ` case Name = 'value';` or ` case Name;`. If there are more than [`MAX_BODY_ITEMS`] cases, the list is truncated with a `// and N more…` comment.
