Support live OpenGUI installation in WorkBuddy

[gofenix]

WorkBuddy 5.5.6 can watch MCP configuration changes while running and can review external Hook changes from /hooks, but the OpenGUI installer rejected every running WorkBuddy process. This made first installation require Command-Q and a separate Terminal command even when the host supported live configuration.

This change allows WorkBuddy 5.5.6+ to remain open, keeps the restart fallback for older compatible hosts, updates the GitHub installation Skill to complete the install in the current task, and guides the user through /hooks and /skills. It retains atomic configuration writes, old-broker upgrade blocking, immutable package directories, receipts, and rollback behavior. The public-testing version is bumped to 0.3.1.

Validation:

• 138 tests passed
• TypeScript build and release validation passed
• packed fresh/offline MCP smoke passed with isolated ADB discovery
• packaged installer passed live 5.5.6 first install, idempotent reinstall, and 5.5.3 restart fallback
• actual running WorkBuddy 5.5.6 preflight returned LIVE_PREFLIGHT_OK without changing configuration
• installation Skill passed quick_validate.py

检查所有共享配置的 WorkBuddy 进程

当机器上存在多个已识别的 WorkBuddy bundle 时，安装器会要求用 --app 选择一个，但这里仅检查所选 bundle 的进程。若另一个正在运行的旧版或副本使用相同的 dataFolderName（例如两个安装都使用 ~/.workbuddy），选择一个未运行的 5.5.6 bundle 就会让预检通过，并在仍由旧宿主使用的配置目录中写入文件，绕过本应触发的 HOST_RESTART_REQUIRED。请像此前逻辑一样检查所有候选 bundle，至少检查所有可能拥有该 config_root 的运行进程，再决定是否允许热安装。
