Record the Crew-stop replay test under FORK.md case 3 #232

FORK.md requires every touch of an upstream file to be recorded in the appended-integration inventory. apps/server/src/orchestration-v2/runtimeLayer.test.ts is listed under case 3, but case 3 names only the delivery-dedup test ("replays an internal thread send without injecting a second message"). The file also carries a J5 Crew test at line 1764, "replaying a Crew stop does not dispatch a second real interrupt", added with the Crew stop work, and the inventory does not mention it.

What should change:

• Add one sentence to FORK.md case 3 naming the Crew stop replay test and what it proves, so a rebase that drops it is recognized as a regression.

Done when case 3 names both J5 tests in that file.
