Separate completed-analysis human presentation

[stef-k]

Summary

• move completed-analysis human rendering into a focused pure formatter
• retain \print_text\ as the compatibility output delegate
• preserve human output byte-for-byte across PASS, REVIEW, and FAIL
• leave JSON, analysis, exits, diagnostics, and management output unchanged

Validation

• focused human-output suites: 64 passed
• full suite: 298 passed
• packaging suite: 12 passed
• representative base/feature human output was byte-identical
• zero-baseline repository audit: REVIEW only, no FAIL
• \git diff --check main...HEAD\

No documentation, thresholds, exclusions, baselines, or user-facing behavior changed.
