fix(kosong): correct type inference when enum/const contradicts expli…

 ## Problem

 When a tool JSON schema explicitly declares a `type` that contradicts the actual values in `enum` or `const` (e.g. `type: 'object'` with `enum: ['move', 'copy']`), `normalizeKimiToolSchema` previously only  inferred the type when it was missing. It did **not** correct a mismatched explicit type, leaving an invalid schema that could propagate downstream.

 ## What changed

 Updated `normalizeProperty` in `packages/kosong/src/providers/kimi-schema.ts` so that when `enum` or `const` is present, the function now:

 1. Infers the type from the enum/const values if `type` is absent (existing behavior preserved).
 2. Corrects the `type` if it is already present but contradicts the inferred type from enum/const values.

 Added a test case in `kimi-schema.test.ts` covering both `enum` and `const` mismatch scenarios.

I first encountered this issue while integrating with xcodebuildmcp. Although the upstream project has since addressed it on their end, I believe applying this
fix at the framework level improves overall compatibility
and prevents similar issues for other integrations.
