* fix(relay): observe Windows PTY child processes instead of answering false `processHasChildren` returned a hardcoded `false` on Windows, and a hardcoded negative is indistinguishable from a measurement. Every close guard reads it as "nothing is running in this pane", so an SSH-to-Windows tab running a build closed with no prompt. Measured on a real Windows SSH host: a live `PING.EXE` under the pane's `cmd.exe` still reported `hasChildProcesses: false`, while the identical harness on Linux reported `sleep` / `true`. Windows has no `ps`, but it does have a process table, and the pane walk over it already existed for the foreground reader. The answer now comes from `queryWindowsPaneProcessInventory`; a table it could not read reports `unverifiable` rather than a fabricated negative. `hasChildProcesses` is a boolean, which cannot hold the third answer, and it is read both as "busy, do not close" and as "the agent took the PTY, safe to type into" — so no single mapping of `unverifiable` is safe for both. The verdict moves to a new optional `childProcessEvidence` member that the close paths read; the boolean keeps its exact meaning for every client that cannot. Cost: `pty.inspectProcess` is the polled path and a relay host has no `@vscode/windows-process-tree`, so its table read falls back to the 1.36s CIM scan. Polling that would reinstate the fork storm the shared table exists to prevent, so only a caller whose answer decides something asks for the scan. * fix(runtime): forward scanChildProcesses through the environment inspection RPC `guardRunningTerminalClose` asks the host to pay for a real child-process read, but the environment path dropped the option before it reached the wire: the renderer sent only `expectedIncarnationId`, and the RPC schema — the shared `TerminalHandle` — silently stripped anything else. A host routing that pane through an SSH relay then declined to scan and answered `unverifiable`, which `inspectionReportsRunningWork` reads as running work. The result was a close confirmation on an idle pane, which is the nag this PR exists to avoid. Forwarded through all four layers: renderer payload, RPC schema, method handler, and the runtime/controller signatures. The schema is a dedicated extension rather than a field on `TerminalHandle`, so `clearBuffer`/`agentStatus`/`isRunningAgent` keep refusing an option they have no use for. The silent strip is not itself the defect — it is what makes a new optional member safe to send to an old host, per docs/reference/remote-wire-compatibility.md. The defect was the schema and its caller drifting inside one version, so the tests pin the registered method rather than the schema alone: pointing it back at `TerminalHandle` compiles, parses, and drops the option. Found by review on #18591. * fix(terminal): teach the shared running-work probe the third child-process answer Rebasing onto main landed `probePtyRunningWork`, which is a better home for this than the close guard: it already speaks `live` / `unverifiable` / `exited`, and it exists so the tab-close and window-close guards cannot drift. The child-process verdict belongs there, not in a parallel predicate beside it. So the mapping moves into the probe and `inspectionReportsRunningWork` is deleted rather than kept alongside. The probe now asks for the scan, and a host that could not observe the pane reports `unverifiable` instead of collapsing onto `exited` -- which is what `hasChildProcesses: false` meant on every Windows relay. The pane-close path is routed through the same probe for the same reason; it was the third caller asking this question through a direct inspect of its own.
