Throwaway diagnostic, do not merge. Runs only the Windows jobs and repeats cgraph_daemon_server_test up to 25 times, logging each graph.json persist attempt and each skip caused by a busy graph_mutex, to explain the windows-release flake "incremental state re-persisted to graph.json" (one failed rename, then no retry for 12 seconds). Will be closed once the logs are read.

[taylorg009]

Diagnostic done: it located the cause of the Windows flake (the test's own non-share-delete reader) and a daemon exit on 'exists: Access is denied'. Both are fixed in #212, which merged after this harness passed 40/40 on each Windows job.
