Expand CLI integration test coverage

[cobusgreyling]

Summary

Expand CLI integration tests beyond createProgram and initProject. Done since filing: bin-entrypoint.test.ts (symlink-safe npx entrypoint) and Claude Code init test.

Still needed

• evidence package (non-interactive, fixture project-root)
• verdict issue (non-interactive)
• ledger why
• policy evaluate

Good commands to test

• evidence package (non-interactive, fixture project-root)
• verdict issue (non-interactive)
• ledger why
• policy evaluate

References

• Fixtures: examples/full-factory/fixtures/
• Existing tests: packages/cli/src/*.test.ts
• Done: packages/cli/src/bin-entrypoint.test.ts

Acceptance criteria

• At least 3 new command integration tests (evidence, verdict, ledger, or policy)
• Tests use temp dirs or fixtures; no interactive TUI
• pnpm test passes
