Summary

• keep web-v2 and cli-v2 session activity visible instead of clearing on run-state polling or stream completion
• preserve final run activity labels through the shared session activity service
• recognize daemon owner ids with startup timestamps as local process leases so dead/restarted daemon leases do not block the next submit

Verification

• yarn -s vitest run src/tests/unit/chat/chat-session-lease.test.ts src/tests/unit/client-shared/session-activity-service.test.ts src/tests/unit/cli-v2/control-plane-session-store.test.ts
• yarn -s typecheck
• yarn -s build
