Rolls the host: str | None = None selector and conn = self._conn(host)
routing across all remaining tools in the 12 mixins (the inventory tools
landed earlier). 97 of 98 tools now accept an optional host to target a
specific managed ESXi server; list_servers is the only exception (it is
the registry itself).
Private helpers that touched self.conn (e.g. ovf NFC/datastore helpers,
nic _get_network_backing, vcenter_ops folder/pool/cluster finders,
host_management _get_host, resources datastore browse/stream) now take a
conn parameter threaded from their tool call sites. Several tools had a
local 'host' variable renamed to avoid shadowing the new selector.
Verified: full server builds (98 tools), and get_host_info/list_hosts
route correctly to two distinct live hosts (205 vs 222).
