Summary

add_recipe(path) and add_recipe_from_string(text) register components written as rows of a tab-separated file (constant, choice, weighted, int, real, with label, depends_on and weight), so components that only draw from a list or a range need no recompiling. They are field() components, so dependencies, ordering, weights, batches and replay work as for code. A bad row throws a core::tsv_error with file, line and column and adds nothing; each row's text is the component's data hash, so a changed recipe changes the signature.

Additive, so a minor version. weighted_choice_component already uses the core's weighted choice (core::discrete), which closes the other half of the plan's entity-generator item.

Test plan

• 10 new test cases (every kind, JSON types and labels, replay and signature, dependencies and weight 0, code depending on recipe keys, replacing, errors that add nothing, a clashing path, a file, batches); 303 test cases pass with clang 22, lint clean
• CI on all compilers
