…n conversion The bool-to-transparent-struct implicit operator wrapped the value in a cast for types other than int/uint but emitted only the cast's closing parenthesis, dropping the one that closes the constructor argument. This produced code like new MyBoolean((byte)(value ? 1u : 0u); which fails to compile. Adds the missing parenthesis and a regression test covering the generate-helper-types boolean transparent struct emission, which previously had no golden coverage.

Fixes #577.
The
bool-> transparent-struct implicit conversion operator wraps the value in a cast ((type)(...)) for backing types other thanint/uint, but theelsebranch inGenerateTransparentStructsemitted only the cast''s closing parenthesis and dropped the one that closes the constructor argument. For abyte;Booleantransparent struct this produced:which fails to compile. Now emits the balanced form:
The
int/uintbranches were already correct (they don''t add the extra cast wrapper).Also adds a regression test exercising the
generate-helper-typesboolean transparent struct emission -- this path had no golden coverage previously, which is how the bug shipped. Full suite: 3709 passing (existing 3708 byte-identical), build 0/0.Note
