test(verify): opt-in 30-minute soak recordings

[richiemcilroy]

Adds opt-in 30-minute soak recordings to the real-capture oracle, for drift, frame loss and sync over a real session length.

What it adds

• CAP_VERIFY_SOAK_SECS=<seconds> (at most 1800) adds two cases to crates/verify/tests/recording.rs:
  • recording/soak/studio-camera: gated Studio, fragmented, with camera, microphone and system audio, and two holds (3 s and 10 s).
  • recording/soak/instant: gated Instant with microphone and system audio, and a 5 s hold.
• Past 30 minutes the microphone's marker indices (12 bits, one every 0.5 s) run out, so the length is capped there.
• Verify recording gains a soak_secs dispatch input, and the job timeout rises to 180 minutes when it is set. Without the variable nothing changes: the cases are not in any tier.

First run

gh workflow run verify-recording.yml -f soak_secs=1800 -f case_filter='recording/soak/*' -f runners=blacksmith, run 38998821647:

	Blacksmith macOS 26	Blacksmith macOS 15
Studio + camera, 30 min	pass	pass
Instant, 30 min	pass	pass
Screen drift vs host clock	+0.01 / -0.01 ms/min	+0.01 / +0.04 ms/min
Camera frames	54,011 of 54,011, all distinct	54,010, all distinct
Microphone markers	3,600 of 3,600	3,600 of 3,600
Camera vs microphone	-6.6 ms	+0.0 ms
Screen vs microphone (Studio / Instant)	+13.0 / +28.7 ms	+35.9 / +19.9 ms

The macOS 26 Instant recording lost one isolated screen frame, within the miss budget; the others lost none. Analysis of a 30-minute recording takes 10 to 20 minutes per case on these runners.

Confidence Score: 5/5

The PR appears safe to merge; both previous findings are fixed and no new actionable issues were found.

Summary

Adds opt-in long recordings to check drift, frame loss, and audio/video sync.

• The recording checks can now run two opt-in, session-length recordings.

Both addressed in dead545: a nonempty CAP_VERIFY_SOAK_SECS that is not a positive number of seconds (1800s, -1) now panics with the value instead of adding no cases, and the comment is down to why the length is capped (the 12-bit microphone marker index).
