Add Integration Test: Verify JSON Output Schema

[Timi16]

Description

Add an integration test that runs the debugger with --output json and validates the output against a defined JSON schema, ensuring the JSON format never silently breaks between releases.

Requirements

• Define a JSON schema for execution output in tests/schemas/execution_output.json
• Run CLI with --output json against the counter fixture contract
• Parse output and validate against schema using jsonschema or similar
• Test covers: return value, budget info, storage diff, events
• Must run in CI

Suggested Execution

1. Branch: git checkout -b test/json-schema-validation
2. Define JSON schema file in tests/schemas/
3. Add integration test using assert_cmd to capture JSON output
4. Validate output with schema
5. Run in CI
6. Commit: test: add JSON output schema validation integration test

Acceptance Criteria

• JSON schema defined and committed
• Integration test runs and passes
• All required fields validated
• Test fails if output breaks schema
• Runs in CI on every PR

I would like to work on this issue because it ensures the debugger’s JSON output remains consistent across releases, preventing silent breakages. I can define the JSON schema, implement an integration test using assert_cmd, validate the output with the schema, and ensure the test runs reliably in CI.
