This PR applies the optional items from the #4267 review (#4267 (comment)). It does not change behavior.

• system-surface-foreground.ts exports SystemSurfaceForegroundReading. The probe signature and both snapshot-route.ts sites use it in place of Awaited<ReturnType<SystemSurfaceForegroundProbe>>.
• The native wedge test block has a comment that says it pins the stale abandon stamp. Its expectation is renamed to secondAbandoned, because the expectation waits for the abandonment, not for the read to drain.

Validation: tested at f9869c4. The check:affected receipt and the native run follow in a comment.

At f9869c4 the rename is right: SystemSurfaceForegroundReading replaces both Awaited<ReturnType<...>> sites with no behavior change. All 17 checks pass and there are no conflicts. The test comment and expectation rename in RunnerTests+SnapshotBridgeTests.swift are unrelated to the type naming, but the PR body discloses them.
