feat: 系统化补齐老 image_generator.py 遗漏的逻辑 + 完整 logtrace

# 启动序列（与旧 main() 1:1 对齐）

新增 core/runtime.py 抽 6 个启动期工具：
  - flush_logs / cleanup_clipboard_tempfiles
  - get_crash_log_path / enable_crash_diagnostics
  - log_system_info / init_logging（RotatingFileHandler 5MB×5）

main_qml.py 完整 8-phase boot：
  Phase 0 enable_crash_diagnostics（faulthandler / excepthook / Qt msgHandler）
  Phase 1 init_logging → logs/app.log
  Phase 2 log_system_info（OS/Python/PySide6/Qt/Pillow/google-genai 版本）
  Phase 2.5 cleanup_clipboard_tempfiles（24h+ 旧文件）
  Phase 3 config 路径 + frozen 时从 bundle 拷贝 + sync_bundled_api_key
  Phase 4 QGuiApplication + 窗口图标（zb100_windows.ico / zb100_mac.icns）
  Phase 4.5 preflight_check（失败弹错退出，不让用户进登录页才撞错）
  Phase 5 业务核心 + Phase 5.5 init_audit_logger 单例
  Phase 6 桥层 + 信号串联
  Phase 7 QML 装载
  Phase 8 aboutToQuit hook → audit shutdown flush

# 完整 logtrace（异常带 stack 落到 app.log）

bridges/* + core/* 所有 try/except 统一改：
  logger.error(f"...: {e}") → logger.exception("...")
  logger.warning(f"...: {e}") → logger.exception("...")
共 24 处。Qt 警告 / fatal / segfault 也通过 enable_crash_diagnostics
落到 app.log 和 crash_log.txt。

# 桥层补齐遗漏的功能（对照旧 ImageGeneratorWindow / LoginDialog）

ImageGenBridge:
  - validateImageFile/validateImageFiles：扩展名 + ≤10MB + QPixmap 完整性，
    与旧 validate_image_file 等价；normalizeFileUrls 内置同样校验
  - toggleSavedPrompt / isSavedPrompt：收藏切换（已收藏点了取消，与旧
    toggle_favorite + check_favorite_status 等价）

HistoryBridge:
  - clearAll：shutil.rmtree(base_path) + 重建空目录 + reset model
    对应旧 clear_history

AuthBridge:
  - _get_public_ip：登录后同步拿公网 IP（3 个 API 兜底各 3s timeout），
    audit log_login 现在带 public_ip，对应旧 get_public_ip

# QML wiring

ImageGenTab:
  - 收藏按钮:  收藏 / ✓ 已收藏 toggle，根据 promptArea.text + savedPrompts 实时切
  - addUrlsValidated 统一"加 + 校验 + 反馈"：用户拖 5 张图 3 张超 10MB 时
    显示"已添加 2 张，丢弃 3 张（不支持 / 超 10MB / 损坏）"
  - 粘贴也走 validateImageFiles，路径 A 拿用户文件时拦截超大

HistoryTab:
  - 顶部加 ️ 清空 按钮（带 MessageDialog 确认）
  - 列表项右键菜单（QtQuick.Dialogs Menu）：在文件管理器中打开 / 复制提示词 / 删除此项
  - 单条删除也走 MessageDialog 确认

# 验证

启动序列 app.log 完整：
  Phase 0..8 全部正确执行，窗口图标已设，audit logger 启动，QML 装载成功。
  系统信息日志记录 PySide6 6.10.1 / Qt 6.10.1 / Pillow 11.1.0 / google-genai 1.52.0。
