fix: preserve runtime configuration references

Projects, channels, conversations, and Agent Runtimes now retain dynamic default references while explicit model selections remain pinned. Compatible fallback resolution stays aligned across settings validation, runtime creation, labels, context metrics, DeepSeek Harness browser routing, and remote project saves.

Prepare the bilingual Desktop 0.12.11 release metadata and keep Agent 0.11.22 as the published remote baseline.

Release note: 修复默认模型与 Runtime 配置变化后项目、通道和对话选择失去跟随关系的问题；显式选择仍保持固定，新请求使用当前兼容配置。
