feat(core): decouple structured output from Groupped trait

2026-06-25T22:08:12+00:00

Introduce `StructuralData` sealed trait and `pack_structural!` /
`group_structural!` / `derive(StructuralData)` macros to control
structured rendering separately from grouping. `Groupped` no longer
requires `Serialize`.

Add shared `MockProgramCollect` and conditional `Groupped` bounds

2026-06-19T17:11:25+00:00

Extract duplicate `MockCollect` implementations into a reusable
`MockProgramCollect` type. Conditionally require `Serialize` on the
`Groupped` trait when the `general_renderer` feature is enabled.

Add `pack_err!` macro for error structs with automatic name field
