What to build

Update ScoreAnswer deserialization in src/jev/primitives.rs to support both sequence arrays and string-indexed maps (such as 0: val0, 1: val1) for legend and probabilities fields. OpenRouter System One serializes score level distributions as maps keyed by level index strings rather than plain arrays, which caused schema validation errors (malformed_answer). The deserializer must accept either wire format, sort map entries by numeric index, and assemble them into standard vectors while preserving strict probability summation and score alignment invariants. Add unit and integration tests with verbatim OpenRouter Score payloads.

Acceptance criteria

ScoreAnswer deserializes legend and probabilities from plain sequence arrays
ScoreAnswer deserializes legend and probabilities from string-indexed maps (such as 0, 1, 2)
Probability sum, highest choice, and weighted score invariants are validated identically across both representations
Unit tests in src/jev/primitives.rs cover real OpenRouter System One score responses
Integration tests in tests/jev_client_tests.rs verify end-to-end score question evaluation against OpenRouter mock payloads
Zero regressions across existing test suite
