test(migrate): regenerate the instant_waits goldens for the never-firing call written as a ref action

[devin-ai-integration]

What and why

go test ./tests/migrate fails on develop (TestInstantBehaviorsWaitingForTheClockAreLedgered and TestGoldenConstructFixtures): the instant_waits goldens are stale. Two PRs that each passed CI on their own branch crossed:

• feat(runtime): perform subactions no succession orders, unordered, during their owner #774 (807fcf5) writes a call that never fires as ref action call : Delay; and extends its ledger note with "…and it is written as a reference action usage, which the activity does not perform".
• fix(migrate): count only written sends as senders, note UI-posted specializations, keep a misrouted send's argument note, name only written clock waits #804 (362fb4a) last regenerated instant_waits.golden.sysml / .golden.report.txt from a branch cut before feat(runtime): perform subactions no succession orders, unordered, during their owner #774 landed, so the goldens still carry action call : Delay; and the shorter note.

develop runs no CI on push, so every PR merging develop in now inherits the failure (seen on #757). This regenerates the two goldens with -update; the diff is exactly #774's intended output for the Send Ack Pause call (_sapCall), nothing else moves:

-                action call : Delay;
+                ref action call : Delay;

How it was verified

• go test ./tests/migrate passes on this branch; on origin/develop (9365f43) it fails with the two goldens differing by only the lines above.
• gofmt -l . prints nothing; python3 scripts/changelog.py check passes. No changelog fragment: test data only, and the behaviour it pins is feat(runtime): perform subactions no succession orders, unordered, during their owner #774's (already covered by its own fragment).

Checklist

• make test and make lint pass locally (the failing package now passes; no source changed)
• Tests added or updated for the change
• Documentation extended where it already covers the surface (none covers test data)
• Changelog entry added as changes/unreleased/<slug>.<section>.md, not as an edit to CHANGELOG.md (not needed, see above)
• baselines regenerated and make docs-counts run if a gate count moved (no count moved)
• No internal work-item labels (waves, slices, F4, K5) in the body, docs, or changelog
