Oc-go-cc, an Open-source proxy that lets Claude Code use OSS models

Summary
This release introduces a robust Windows autostart fix and a built‑in self‑update mechanism, enabling users to keep routatic‑proxy current directly from the command line. Enhancements to autostart handling, command‑line formatting, and background process logging improve reliability on Windows, while the new updater package adds version comparison, checksum verification, and GitHub API integration.

• Enhance User‑Agent handling – set a custom User‑Agent for GitHub API requests.

Bug Fixes

• Update .gitignore – include .kimchi and remove obsolete documentation files.
• Replace ping with timeout – improve backup deletion reliability on Windows.

Improvements
