🚀 v6.6.6 — Internationalization, Map Runtime & Location Resilience

🌐 Major improvements to UI internationalization, runtime language switching, map preview runtime behavior, and location assignment reliability.

Added TranslationManager as a runtime service on RuntimeContext, backed by the ui.language setting and runtime languageChanged refresh signals.
Added bundled Qt translation resources for German and Simplified Chinese, including languages.json metadata and package-data coverage for .ts / .qm resources.
Added a language menu under Settings with English, Deutsch, and 简体中文 choices; English remains the fallback language.
Migrated major GUI surfaces to translated text, including main menus, status-bar feedback, info panel, People dashboard, album navigation, gallery context menus, detail/player controls, share/export feedback, face overlays, edit sidebar controls, and the standalone map preview entry point.
Added locale-aware GUI formatters for dates, integers, decimals, and file sizes so translated surfaces do not depend on the host system locale.

Added Python-aware i18n extraction through tools/extract_i18n_strings.py and scripts/i18n_extract.sh, covering src/iPhoto/gui and src/maps.
Added scripts/i18n_compile.sh for rebuilding .qm translation resources with pyside6-lrelease.
Added tools/check_i18n_strings.py and architecture tests to block direct English literals in high-risk GUI APIs such as setText, setToolTip, QAction, dialogs, and status messages.
Added Apple Photos-aligned edit terminology notes under docs/requirements/i18n/.
Added a long-term i18n UI text guardrail under docs/misc/.

Extended standalone map preview backend selection with explicit auto, native, python, and legacy modes.
Added runtime diagnostics for map preview backend selection.
Hardened map surfaces with opaque backing colors and full-update repaint behavior.
Added optional map diagnostics through runtime flags.
Improved marker rendering inside supported map passes.

Assign Location now persists the selected place to global_index.db even when ExifTool is missing or original file metadata writeback fails.
Added user-facing warnings for missing ExifTool or failed GPS writeback while keeping the local database assignment intact.
Sanitized metadata updates before JSON storage so non-serializable third-party values cannot corrupt asset rows.

🌐 针对 UI 国际化、运行时语言切换、地图预览运行时行为以及位置分配可靠性进行了全面优化。

新增 TranslationManager，并将其作为 RuntimeContext 上的运行时服务，由 ui.language 设置和运行时 languageChanged 刷新信号驱动。
新增内置 Qt 翻译资源，支持德语和简体中文，并包含 languages.json 元数据以及 .ts / .qm 资源的 package-data 覆盖。
在 Settings 下新增语言菜单，支持 English、Deutsch 和简体中文；English 仍作为默认回退语言。
将主要 GUI 界面迁移为可翻译文本，包括主菜单、状态栏反馈、信息面板、People 面板、相册导航、图库右键菜单、详情页 / 播放器控件、分享 / 导出反馈、人脸覆盖层、编辑侧边栏控件以及独立地图预览入口。
新增支持区域设置的 GUI 格式化工具，用于日期、整数、小数和文件大小显示，避免翻译界面依赖宿主系统语言环境。

新增面向 Python 的 i18n 字符串提取工具 tools/extract_i18n_strings.py 和 scripts/i18n_extract.sh，覆盖 src/iPhoto/gui 与 src/maps。
新增 scripts/i18n_compile.sh，用于通过 pyside6-lrelease 重新生成 .qm 翻译资源。
新增 tools/check_i18n_strings.py 和架构测试，阻止在 setText、setToolTip、QAction、对话框和状态消息等高风险 GUI API 中直接写入英文文案。
在 docs/requirements/i18n/ 下新增对齐 Apple Photos 的编辑术语说明。
在 docs/misc/ 下新增长期 i18n UI 文案防护规范。
