🐞 Fixes

Fix TypeError: z.xor is not a function for consumers on zod < 4.3

The SDK's finetune schemas used z.xor([z.number(), z.nan()]) in 8 places, an API only available in zod ≥ 4.3.0. The package declared "zod": "^4.0.17", so consumer projects whose tree resolved zod to a 4.0.x / 4.1.x / 4.2.x version crashed at runtime when finetune schemas loaded.

Two coordinated changes:

• Replaced z.xor([z.number(), z.nan()]) with z.union([z.number(), z.nan()]) in packages/sdk/schemas/finetune.ts. In zod v4, z.number() rejects NaN by default, so z.number() and z.nan() are disjoint — z.xor and z.union are semantically identical here.
• Bumped the declared zod floor from ^4.0.17 to ^4.3.0 to align the declared range with the version of zod the SDK is actually built and tested against.

Consumers who hit _zod.z.xor is not a function on 0.9.1 will be unblocked at runtime after upgrading to 0.9.2.
