Add direct tests for solverforge-console

[blackopsrepl]

Summary

solverforge-console appears to have little or no crate-local test coverage.

Problem

This crate configures tracing and subscriber behavior, which is small in size but easy to break subtly.

Why This Matters

Initialization, filtering, and formatting behavior should be explicitly covered because regressions here are easy to miss.

Proposed Work

• Add smoke tests for idempotent initialization.
• Add tests for default filters.
• Add tests for formatting behavior where practical.

Acceptance Criteria

• solverforge-console has at least a minimal direct test suite.
• Repeated initialization behavior is explicitly covered.

Derived from PR #3 (PRODUCTION_REVIEW_ISSUES_2026-03-20.md).

[blackopsrepl]

Resolved by #22.

We added direct solverforge-console coverage for solve lifecycle, progress, and trace-step formatting by driving the formatter through real event recording, including the production move_index and element_count payloads.
