refactor(docs): co-locate k8s/proxmox docs with their code + fix broken perf paths

Docs moved from docs/k8s -> k8s/docs and docs/proxmox -> proxmox/docs to sit
beside their code. Updated all cross-references (docmap, STATUS, README, AGENTS,
k8s README). Fixed SCRIPT_DIR path resolution in 3 perf scripts broken by the
reorg (deploy-check/and-fix/finish-host pointed at root/scripts instead of
perf/scripts). Registered the new top-level proxmox/ dir in all listings.
