[COVI-10] Expose conversation metric outputs in the CLI

[callumreid]

Summary

• add --include-metric-outputs <METRIC_ID> to coval conversations list
• map the option to the generic include=metric_outputs&metric_id=... API contract while preserving list filters, ordering, and page size
• deserialize full metric outputs, including structured result.raw_values, into the conversation JSON response
• remove the specialized failure-breakdown command and response models so aggregation semantics stay in consumers such as Covi

Example

coval --format json conversations list \
  --include-metric-outputs 6zhcrtiNmPrRsbXHoXEoqc \
  --page-size 50

Use normal list filters and pagination to retrieve additional pages.

Validation

• cargo test: 97 CLI tests + 2 unit tests passed
• focused wire-contract test passed
• cargo clippy --all-targets --all-features -- -D warnings passed
• cargo fmt --check passed

Dependency

• coval-ai/backend#5678

Walkthrough

Conversation listing now supports an optional metric ID that requests full metric outputs. The client adds the required query parameters, and the conversation model deserializes optional metric output data. The CLI conditionally uses the new client method while preserving standard listing behavior. A CLI test verifies pagination, query parameters, and nested metric output fields.
