PLUGIN ECOSYSTEM ROLLS FORWARD AS BUFFA CUTS HEAP ALLOCATIONS

Buffa shipped a codegen overhaul that makes inline storage the default for message fields, eliminating per-field heap allocations across the board while the plugin pipeline churns through dependency updates.

The buffa team landed a significant performance win [1] by making `PointerRepr::Inline` the default for singular message fields. This means codegen now emits inline storage for every non-recursive field, laying them out as `Option<T>` with zero additional heap pressure. Recursive fields are detected automatically at codegen time and stay on `Box`, so you never lose type safety. This is the kind of change that compounds across a large codebase. Meanwhile, the plugin ecosystems are in steady state. The official plugins desk processed five dependency bumps [2][3][4][5][6], each validated through `claude plugin validate` before the PR landed. The healthcare plugin sync [7] merged automatically to publish changes to the marketplace. Over on the community side, five more plugins got SHA bumps [8][9][10][11][12], all pre-validated and ready for review. Nothing broke. Everything moved.
