examples(grant-scoring): add schema validation for pilot fixtures

[karagozemin]

Summary

Validate the grant-scoring fixtures in examples/grant-scoring/fixtures against a shared schema so malformed pilot data fails fast with a clear message.

Motivation

Pilot onboarding depends on well-formed fixture data; silent shape mismatches surface as confusing runtime errors deep in scoring.

Acceptance criteria

• Schema definition for the pilot fixture shape.
• Validation run in the example entrypoint and in tests.
• Tests for one valid and two invalid fixtures.
• Documented in the example README.

Good day, Maintainer. I have experience working with data validation and backend development, and I'd like to work on this issue. I'll review the existing grant-scoring pilot fixtures, implement robust schema validation to ensure fixture integrity and consistency, verify compatibility with the current project structure, test for edge cases and validation failures, and submit a clean, well-documented pull request. I would appreciate being assigned this issue.

Hello Maintainer,

I'd like to work on this issue. I understand the goal is to add schema validation for the grant-scoring fixtures, ensure validation runs in both the example entrypoint and tests, cover valid and invalid fixture scenarios, and update the documentation. If assigned, I'll implement the requested changes, test them thoroughly, and submit a clean pull request.

Thank you for your consideration.
