fix(vscode): count pending submission time

[marius-kilocode]

#11103 makes the first prompt and Thinking spinner appear immediately in a new Agent Manager Local tab. While that tab is still waiting for the backend to create its real session, however, the backend status remains idle. The elapsed indicator interpreted that idle status as inactive, so users could see a spinner with no timer for several seconds, followed by the timer suddenly appearing at a higher value once session creation finished.

Treat a pending submission as active for elapsed-time tracking. The timer now progresses visibly from the moment the prompt is sent and continues from the same start time when the pending tab is promoted to a real session, rather than appearing late or resetting during the handoff.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The fix is correct and well-scoped. The extracted tracksElapsed predicate cleanly captures the two-phase logic: keep the timer alive while a draft submission is pending (before a backend session ID exists), then defer to backend status once the session is promoted. The type predicate return type (since is number) is a nice touch — it narrows the type for the caller.

Tests cover all four meaningful cases (pending-only, each active backend status, idle-with-no-pending, missing since) without duplicating implementation logic.
