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.

# finish-host.sh - applies ALL remaining changes to a host and verifies.
|
||
#
|
||
# Steps:
|
||
# 1. Start all VMs (triggers NFS lazy-mount)
|
||
# 2. Wait for NFS mounts to appear
|
||
# 3. Verify NFS nconnect=4 + noatime
|
||
# 4. Apply bond0 xmit_hash_policy=layer3+4
|
||
# 5. Full end-to-end verification
|
||
#
|
||
# Usage: bash finish-host.sh <host> [--apply]
|
||
# Default is dry-run (starts VMs + shows what bond change would do, but doesn't edit interfaces)
