refactor(schemas): consolidate inline pagination objects into PaginationSchema

[shwetank-dev]

PaginationSchema exists in packages/schemas/src/api-responses.ts as a reusable shape, but several response schemas inline the same object instead of referencing it.

Duplications

PaginationSchema is defined at api-responses.ts:28:

export const PaginationSchema = z.object({
  limit: z.number(),
  offset: z.number(),
  has_more: z.boolean(),
});

It is used correctly at api-responses.ts:403 (MyPackagesResponseSchema) and api-responses.ts:422 (UnclaimedPackagesResponseSchema), but inlined in:

• api-responses.ts:223 — BundleSearchResponseSchema inlines pagination: z.object({ limit, offset, has_more })
• skill.ts:152 — SkillSearchResponseSchema inlines pagination: z.object({ limit, offset, has_more })

Suggested fix

Replace the two inline objects with PaginationSchema. For skill.ts, import it from api-responses.js.

Notes

Pure refactor — no behaviour change, no breaking change to inferred TypeScript types.
