docs: make the runbook resume-ready after the standalone session

- ManualTests.md resume checklist: current batch-B guest state (64 ROM systems, all standalone emulators + BIOS/keys), BUG-14/15 committed but not redeployed, remaining work narrowed to the full 33-scenario pass, the two live re-verifications and the unexercised manual items; item 9 now states the tree is clean through d181805.

- docs/gui-test-harness.md: harness file table gains vm-systems2.json/seed-batch2.py/fix-arrays.py/launch-one.py, the coverage map and the resume paragraph record the standalone session outcome.

- docs/manual-tests.md: the Linux/macOS launch pipeline item now records the verified CHD->ISO conversions (byte-identical to chdman, temp ISO cleaned up, Xbox boots), the DOSBox temp conf, and the no-config-injection confirmation across the new emulator launches.
