Records the status the API reports right after pause and whether the terminal still runs a command, since the first staging run's client stayed connected for a full minute after pause. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>

Review comments at @web/scripts/cloud-vm/dogfood-journey.mjs:
- Around line 550-551: Update the paused-terminal check around `typeLine()` and
`waitForScreen()` to measure its five-second deadline from pause completion,
accounting for time spent waiting on the write. Pass only the remaining time to
`waitForScreen()` so a late command cannot be reported as live during the pause.
- Around line 548-549: Wrap the status observation using api() in a local
try/catch so fetch and timeout rejections set result.statusAfterPause to an
unavailable value and record a concise note via note(). Allow the remaining
pause checks to continue without marking the overall journey failed.

Use a post-resume output boundary for pausedKeystrokesRanAfterResume.
waitForScreen() delegates to terminal.wait, which checks the current screen before waiting for changes. If ${marker}-4 appears after the five-second window but before resume, the post-resume wait can match that existing output and record true incorrectly. Use a stream offset or revision captured at resume, or otherwise distinguish output produced after resume.

Summary
The first staging run of the Cloud dogfood journey (run 36402933616) passed every step. After
POST /api/vm/:id/pausereturned, though, the headless cmux-tui client stayedconnectedfor the full 60 s it was watched. With a 5 s heartbeat and a 15 s timeout, a frozen machine should show up asreconnectingwithin about 20 s. So either the provider pauses later than the API says, or the machine keeps running.This adds two facts to the pause leg:
statusAfterPause: the statusGET /api/vm/:idreports right after pauseterminalLiveWhilePaused: whether a command typed into the VM terminal still runs within 5 sBoth are recorded and never fail the run. Tooling only (
