Add a conditional TDD Evidence field to the implementer report format so controllers can verify RED and GREEN output when TDD was required.
The field asks for the command run, relevant RED/GREEN output, and the expected RED failure reason rather than raw full logs.
Fixes#994.

Verified against OpenCode source (packages/opencode/src/tool/todo.ts).

CLAUDE_PLUGIN_ROOT and emit only the appropriate field.
