fix(launch): restore staging time in the signed launch window

[Mathis (echobt)]

task8-deps stops staging at cutoff - (qualification + hard margin), so the
11460 s window left 60 s for host deps and failed with
remote_absolute_deadline_exhausted. Window back to 13200 s and the admit
guard counts the 1800 s staging budget.

Summary by CodeRabbit

• Bug Fixes
  • Updated the minimum launch-window requirement to 13,200 seconds, accounting for dependency staging, qualification, and a safety margin. Shorter windows continue to fail with the existing error.

📝 Walkthrough

The CUDA launch script increases its default window to 13,200 seconds. The admission-stage minimum check also requires 13,200 seconds before CUT. Insufficient windows continue to fail with the existing error.

Changes: CUDA launch window

Layer / File(s)	Summary
Launch window requirement scripts/launch_cuda_run.sh	The default window increases to 13,200 seconds, including 1,800 seconds for dependency staging. The admission-stage minimum before CUT increases to 13,200 seconds. Insufficient windows still produce the existing error.

Dependency staging can run out of time before completing and fail the launch. The default window should account for time spent before staging begins.

Increase the launch window before checking the staging floor.

CUT is set to A + WINDOW, but the staging check runs later. If that check requires NOW + 13,200 <= CUT, the default WINDOW=13,200 fails after any elapsed time between admission and staging. Set the default window to at least 15,000 seconds, or derive it from the admission-to-staging allowance, so staging retains 1,800 seconds followed by qualification and margin.
