* ci(linter): add renovate/prefer-zod-nullish rule
Add a custom oxlint rule that flags zod chains calling .optional() and
.nullable() adjacently (in either order) and suggests .nullish(), which
is equivalent (both accept undefined | null in zod v4).
Fix all 26 pre-existing violations across 6 schema files.

* ci(linter): prefer schema-utils Nullish over zod .nullish()
Rename prefer-zod-nullish to prefer-nullish-util and extend it to flag
.nullish() itself, including the standalone forms z.nullish(x) and
z.optional(z.nullable(x)). Migrate all call sites to Nullish() and
DeepNullish() from schema-utils, which normalize null to undefined in
parsed output. Schemas with more than one nullish position are wrapped
in DeepNullish(); nullish object properties with nullish members use
Nullish(DeepNullish(...)) to keep the optional property type marker.
Spec files are exempt (result.spec.ts intentionally tests
null-preserving parses). Spec assertions expecting null in parsed
output were updated to undefined. Note: docker manifests with an
explicit "mediaType": null are now accepted and treated like an absent
mediaType instead of failing the discriminated union.
