gnhf 0.1.39 renders meteors beside content

This is mostly a cosmetic release, but it strengthens gnhf's identity instead of hiding behind generic polish language.

• –The core value prop remains the same: run coding agents on a repo, keep successful iterations, and commit each win to a dedicated branch
• –Support for Claude Code, Codex, Rovo Dev, OpenCode, Copilot CLI, and Pi makes it a wrapper layer across multiple agent stacks
• –A meteor renderer does not change the product's mechanics, but it makes the terminal experience more memorable and easier to demo
• –The project is leaning hard into the “overnight autonomy” workflow, which is a real niche for long-running refactors and test-heavy chores
