   Added #[tsify(rename = "...")], which renames the generated TypeScript declaration and nothing else — references from other types still emit the Rust

   • Added #[tsify(rename = "...")], which renames the generated TypeScript declaration and nothing else — references from other types still emit the Rust ident, so point them at the new name with #[tsify(type = "...")] at each reference site. Cannot be combined with type_prefix or type_suffix. Resolves #70, which had been blocking the 0.4 → 0.5 upgrade for anyone with two same-named types in different modules
   • type_prefix and type_suffix no longer rename type parameters. A type parameter has no declaration for the affix to rename, so #[tsify(type_prefix = "Ts")] struct Wrapper<T> { x: T } declared export interface TsWrapper { x: TsT; } — the parameter dropped, and TsT never declared anywhere. It now declares export interface TsWrapper<T> { x: T; }. If you use either attribute on a generic type, its .d.ts changes. There was no correct way to use the affix on a generic type before this, so nothing that type-checked without skipLibCheck is affected
   • type_prefix and type_suffix no longer reach the tag literal of an internally-tagged type. That value comes from serde, which was never told about the affix, so #[serde(tag = "kind")] #[tsify(type_prefix = "A")] struct Config declared kind: "AConfig" where serde has always serialized "Config". It now declares kind: "Config". If you narrowed on the old literal, that code compiled and never matched at runtime; it is now a compile error. Applying either attribute to only some of your types still emits references to names that were never declared — that half of #94 is still open
