fix: prevent managed runtime stalls during file changes

Automatic native Git snapshot diffs could block concurrent OpenCode sessions
after broad rewrites or line-ending conversions. Managed desktop and Agent
profiles now skip snapshots that GoodBuddy does not use, while preserving
file tools, native subagents, workspace Git operations, and Ask/Execute rules.

Drain otherwise-unused Continue utility-host stdout to prevent console output
from filling the pipe and blocking requests. Correct the lifecycle regression's
body observer to watch the underlying reader rather than a buffered wrapper.

Prepare Desktop 0.12.10 and Agent 0.11.22 with aligned bilingual notes and
feature documentation. Existing runtimes require restart or Agent update.
Full desktop UI before/after and Linux Agent production-path checks passed;
3626 tests passed, with 61 existing platform/manual skips.

Release note: 修复批量文件改写或换行转换后的托管 OpenCode 并行停顿，以及 Continue 控制台输出阻塞；本机升级重启后生效，远程项目请配套更新 Agent。
