Hubo v0.4.5

What's changed

• Add hubo-review: one reviewer produces the canonical review while a critical reviewer challenges every finding and omission.
• Keep both Hubo skills explicit, conversation-visible, and portable across Claude Code, Codex, GitHub Copilot CLI, and OpenClaw.
• Remove the experimental Audit mode and make Review self-contained for standalone installation.
• Refresh the English and Simplified Chinese usage documentation.

Validation

• Both skill validations passed.
• Codex plugin validation passed.
• Claude plugin and marketplace validation passed.
• Standalone discovery found exactly hubo and hubo-review.
