mrcharles 0e8197fd2d refactor(plant): two-layer snmp sensors — raw transport + semantic templates [#344] 
HA 2026.8 rejects ANY non-numeric native_value on a unit-bearing snmp
sensor at entity ADD (host down at boot renders ''/'unknown'/'None' as
strings) — unit-bearing adds crash and the entity vanishes until manual
reload. Raw layer now carries no unit (validation off); semantic template
layer carries unit + device_class under the original unique_ids so
entity_ids, dashboards, and automations are unchanged.

sensor:
# ARCHITECTURE (2026-09-02, HA 2026.8) — two layers, do not re-merge:
# RAW layer (platform snmp, below): transport only. NO unit_of_measurement
# and NO device_class — HA 2026.8 raises ValueError at entity ADD when a
# unit-bearing sensor's native_value is non-numeric (host down/asleep at
# boot renders '' or the literal string 'unknown'; even {{ none }} is
# stringified to 'None'). Unit-bearing adds CRASH and the entity vanishes.
# SEMANTIC layer (template: below): carries unit + device_class under the
# ORIGINAL unique_ids (registry keeps the original entity_ids so dashboards
# and automations are unaffected). Template platform degrades to unknown
# gracefully. value must never render empty — guard with is_number().
# --- RAW SNMP transport (lm-sensors / drac / pdu extends) ---
