De-flake ShardedDaemonProcessSpec multinode spec (#8431) - #8492
Merged
Conversation
Backport of dev commit dcd9acb to v1.5, scoped to the ShardedDaemonProcessSpec rewrite. The Player.cs / MultiNodeTestRunner.cs portions of akkadotnet#8431 were already delivered to v1.5 in the MNTR conductor reliability backport (akkadotnet#8488), so only the spec change is taken here. Rewrite the ShardedDaemonProcess multinode spec to be async and resistant to slow-CI barrier timeouts: - task-returning TestKit methods throughout (no sync-over-async) - single cluster-wide collector probe on 'first' so shards reallocated during cluster settle are reported correctly - fish for a complete distinct-ID set instead of assuming 4 messages - raise testconductor barrier-timeout to 60s for slow agents - fix HOCON brace nesting that dropped keep-alive-interval Adapted to v1.5: AwaitClusterUpAsync(CancellationToken.None, ...) to match the v1.5 TestKit signature. (cherry picked from commit dcd9acb)

Backport of #8431's ShardedDaemonProcessSpec rewrite to v1.5, scoped to the spec change only. The Player.cs / MultiNodeTestRunner.cs portions of #8431 were already delivered to v1.5 in the MNTR conductor reliability backport (#8488), so only the spec is picked here.
