`mount_points = ["/hostfs"]` filtered for a literal /hostfs mountpoint
that never exists in /proc/mounts: gopsutil with HOST_MOUNT_PREFIX
strips that prefix and reports real host paths (/, /boot, /home).
The filter matched zero, so no `disk` rows were emitted at all.
`interfaces = [..., "wlan*"]` missed modern wireless naming (wlp*,
wlx*). Replace with broader globs (`eth*`, `en*`, `wl*`, `wwan*`,
`bond*`) that match all physical/bonded interfaces while still
excluding docker bridges, veth pairs, lo, and tun/tap.
Add telegraf-entrypoint.sh to render telegraf.conf from the template
(replacing @@HOST_TAG_BLOCK@@ and @@ZFS_BLOCK@@ markers via awk) and
exec telegraf. Add test-telegraf-entrypoint.sh with 8 offline tests
(10 assertions) covering marker substitution and required-env validation.
Fix run() stderr redirect from >/dev/null 2>&1 to >/dev/null so that
entrypoint error output reaches the T6-T8 assertion captures.
