## Summary - Added doc comments across the codebase: `pkg/lambda`, `pkg/saccharine`, `pkg/codec`, `pkg/engine`, `pkg/iterator`, `pkg/set`, `pkg/convert`, `internal/registry`, and `cmd/lambda`. - Made lambda and saccharine expression structs use public fields instead of getters, matching `go/ast` conventions. - Removed superfluous constructors for saccharine and lambda expression/statement types in favor of struct literals. - Consolidated saccharine token constructors into a single `NewToken` function. - Removed the unused `trace` package. ## Test plan - [x] `go build ./...` passes. - [x] `go test ./...` passes. - [ ] Verify `go doc` output renders correctly for documented packages.
