Reorganize the merged KNELServerBuild + PFVCluster repo:
provisioning/ server provisioning (was ProjectCode/ +
Project-Includes/ + Project-ConfigFiles/)
tests/ test suite (was Project-Tests/)
perf/ Proxmox perf scripts (was top-level *.sh + scripts/)
docs/ all documentation (was ProjectDocs/ + PROJECT.md +
K8S.md + TODO.md)
dns-cluster-setup/ Technitium DNS cluster (unchanged)
netinfra/ netinfra audit scripts (unchanged)
switches/ switch configs (unchanged)
vendor/ vendored KNELShellFramework (unchanged)
Update all internal path references from old directory names
(ProjectCode/, Project-Includes/, Project-Tests/) to the new ones
(provisioning/, tests/) across all scripts.
