fix: make Host updates simple and fast

Host repair could fail while adopting the published OpenCode Runtime, then
repeat package and payload verification and carry durable metadata snapshots
for recovery. Host preparation now verifies each acquired compound archive
once, adopts signed Agent and Runtime metadata without rereading payload trees,
and retries failed work by cleaning staging and preparing fresh.

The desktop and Agent versions are advanced to 0.11.9 with the approved
bilingual release notes. Remote Projects remain a disabled-by-default technical
preview, Agent packages remain separate Linux x64/arm64 releases, and this
release has no LoongArch preview.

Release note: 修复 Host 更新采用失败，移除重复远端包体校验，并将中断恢复简化为清理暂存后重新准备。
