Equivalence Reasoning

stylistic

The agent patch implements the required type-level change to accept readonly discriminated-union option collections (in both `src/types.ts` and `deno/lib/types.ts`) and updates tuple typing for `create` to `readonly`, matching the intended behavior. It also adds tests proving readonly tuple usage and inferred union typing. The only difference from gold is using a readonly default generic type, which is behaviorally aligned.

Code Review

correctness: 4/4introduced bug risk: 4/4edge case handling: 4/4maintainability idioms: 4/4

The agent patch appears to satisfy the intended readonly discriminated-union change with low risk: core type constraints were widened appropriately and targeted tests were added in both src and deno test suites.
