- TestTagUserMutualExclusivity and TestUserToTagCrossIdentityGrant:
add ReduceFilterRules after compileFilterRulesForNode to match the
production filter pipeline in filterForNodeLocked. The compilation
step produces global rules for all ACLs; ReduceFilterRules strips
them down to only rules where the node is a destination.
- containsSrcIP/containsIP helpers: use util.ParseIPSet to handle
IP range strings like "100.64.0.1-100.64.0.3" produced by
ipSetToStrings when contiguous IPs are coalesced.
