The MCP create_node/update_node inputSchema only advertised
type/label/ip/hostname/status (plus parent_id on update), so LLM
clients could not set documentation/hardware fields the backend
already validates and stores.
Mirror NodeBase/NodeUpdate by spreading a shared _NODE_FIELDS schema
into both tools: os, notes, mac, check_method, check_target, services,
cpu_count, cpu_model, ram_gb, disk_gb, show_hardware, container_mode,
custom_icon, properties. type stays an enum of canonical node types.
_dispatch already forwarded args verbatim, so no dispatch change.
Also extend _slim_canvas NODE_KEEP so get_canvas round-trips the new
documentation fields the LLM can now write.
Refactor tool definitions into a module-level TOOLS list for direct
schema assertions in tests.
