0.32.0-beta.0 (2025-12-18)

Nitro 0.32 is a big release:

new DX/convenience features (such as making all C++/Swift structs Equatable/operator==, or making Kotlin structs/enums extensible via companion object)
huge performance improvements by caching jsi::PropNameID (measured ~30% faster performance with structs)

Generated Swift structs' individual properties should be read-only. Their setters have been removed to make this more obvious.
