migrate-to-shoehorn

Replace `as Type` with fromPartial() from @total-typescript/shoehorn, which accepts partial data while keeping type checking. For intentionally wrong data written as `as unknown as Type`, use fromAny() instead, then run your type checker to verify.

Shoehorn creates type-safe partial test data in TypeScript. It lets you pass only the properties a test cares about instead of faking entire large objects, while preserving autocomplete and compile-time checks. It is intended for test code only, never production code.

Use fromPartial() for partial data that still type-checks, fromAny() for intentionally wrong data such as error-case testing while keeping autocomplete, and fromExact() to force a full object that you can later swap to fromPartial.

No. Shoehorn is designed for test code only, where partial or intentionally incorrect data is acceptable. Using it in production code would bypass TypeScript's type guarantees where real data integrity matters.

Run grep with a pattern like `grep -r " as [A-Z]" --include="*.test.ts" --include="*.spec.ts"` to locate capitalized type assertions in test files. Then replace each match with the appropriate shoehorn helper and add the import.
