Summary

• fetch all immediate children for the bounded vnsLIfCtx queries instead of requesting a remote redirect class unavailable on APIC 5.2
• preserve local and remote redirect-policy evaluation in the existing client-side logic
• classify APIC code 12 Unknown class responses as unsupported classes

Fixes #486

Evidence

On calo-a APIC 5.2(8i), the Check 105 subtree selector returns code 12: Unknown class vnsRsLIfCtxToRemoteSvcRedirectPol. The same parent query succeeds when the subtree-class projection is omitted.

Testing

• focused unit tests: 43 passed
