Add machine-readable CI state classifier for ADK contributor workflows #4604
Description
Problem
CI check interpretation is inconsistent and can misclassify non-triggered jobs as pass.
Why now
Multi-repo operations require normalized check-state output for deterministic triage.
Current behavior is insufficient
Contributors rely on manual interpretation of check output, which is error-prone.
Expected behavior
Provide a deterministic classifier utility that emits machine-readable CI state categories.
Acceptance criteria
- JSON output with normalized state and source evidence.
- Categories:
failed,pending,no checks,policy-blocked. - Clear distinction between product regressions and policy/account gates.
Validation
- Add tests for each classification path.
- Validate deterministic output shape.
