R0.3 system-param over gRPC is now LIVE-VERIFIED against the real 2023 R2 server
(returned HistorianVersion), alongside the re-confirmed read chain and probe.
The apparent NTLM round-1 SEC_E_LOGON_DENIED "blocker" was a test-harness
credential-parsing bug, not a server/account/SDK issue: the gitignored creds
file stores quoted values and the env-setup must strip surrounding quotes before
exporting HISTORIAN_USER/PASSWORD. With quotes stripped, the NAM domain account
authenticates and the full chain passes. The round-failure diagnostic added
during the hunt (HistorianNativeHandshake.DescribeError) is kept.
