Anti-slop migration

Use after the anti-slop Oxlint plugin is installed and the repo has existing findings. Completion means zero configured lint diagnostics, reached by fixing contracts at their root. A finding is never fixed by a semantic loophole, an unsafe cast, any, a suppression, or a weaker severity.

Order of categories

Fix categories in dependency order. Later categories shrink as earlier contracts improve:

1. no-object-parameters
2. no-reflect-get / no-reflect-apply
3. no-chained-type-assertions
4. no-shape-in-symbol-names
5. no-unknown-returns
6. no-known-value-widening
7. no-conditional-empty-object-spread
8. no-unknown-parameters
9. no-unsafe-dictionary-type
10. no-runtime-typeof
11. require-safety-comment-for-type-assertion
