fix: handle Windows terminal PID readiness and remove unstable tests - #778
Fix Windows terminal cleanup when node-pty initially reports PID 0 while its ConPTY worker is starting.
Changes
Capture the terminal PID and process identity once the PID is available; bound startup waiting during close and retain existing identity-fenced cleanup.
Add four deterministic regression cases for PID readiness and startup timeout.
Remove the requested timing-sensitive Updater handoff, relay tool-output HTTP, and ACME issuance/disk-reuse tests, including unused helpers.
Validation
Focused terminal suites: 93 tests passed on macOS.
Local npm test: passed (9,790 Vitest tests passed / 67 skipped, 592 Web tests passed, Rust suites passed). This run included unrelated uncommitted worktree changes, which are NOT included in this PR.
Focused Prettier checks and git diff --check: passed.
ESLint ignores the imported terminal source and regression test paths.
Native Windows verification remains pending CI; local regression tests simulate Windows PID readiness.
Scope
Contains only commits a4449cd2c and 5d6b7f23c. No unrelated Web steering worktree changes are included. No linked issue.
Windows terminal cleanup can fail before releasing its resources, and several queue, history, and recovery risks remain open. The removed preview test also leaves an important download-in-progress behavior unprotected. Resolve or explicitly accept these risks before merging.
The reason will be displayed to describe this comment to others. Learn more.
Retry identity capture until the root is observable
When ConPTY publishes a positive PID slightly before the Windows process snapshot can return that process (or if the first snapshot throws), this method records processId but leaves rootIdentity undefined; the guard then permanently suppresses every later capture attempt. An immediate terminate() consequently cannot adopt descendants and stopShellWindows() falls back to the bare node-pty kill path that this module documents as unreliable without a parent console, so cleanup can throw and leave the terminal process tree running. Keep retrying the identity lookup while rootIdentity is unset, including during the readiness wait.
建议增加一个用例：第一次 tree 返回空数组，之后返回身份。然后断言清理仍使用带身份保护的 signalProcess。

处理缺少 clientUserMessageId 的原生队列项。
快照会显示这类队列项，并使用 item.id 作为回退值。如果存在活动 Turn，sendNativeQueuedMessage 却会返回 -32602 Queued message is no longer available，用户无法 steer 该队列项。无活动 Turn 时，代码会将该队列项交给 thread/queue/start。
请支持缺少该字段的队列项，并补充活动 Turn 的测试。
