Work buddy git 修复

Diagnose and repair git authentication and push/fetch failures inside WorkBuddy (Windows portable Git). Covers "terminal prompts disabled", "could not read Username", "Authentication failed", stored credentials that git still refuses to use, crashed or silently failing Git Credential Manager, credential helper selector popups, first-time GitHub credential setup, proxy-related auth failures, and GitHub connector 403 "Resource not accessible by integration". Core fix switches the credential helper to wincred, which reads the token already stored in Windows Credential Manager with zero external dependencies. Guides the user through every popup (helper selector, browser OAuth, UAC) and every sandbox-escalation approval in plain language; tokens are never displayed and never left behind. Use when git push fails with auth errors, when git asks for a username despite stored credentials, or when the user asks to fix git auth / configure Git Credential Manager / 修复推送失败 / git 认证失败 / 配置凭据 / 推送需要授权.
