Python Params uses snake_case; the C++ camelCase call raised
AttributeError, killing thermald_thread at the exact moment of shutdown.
Result: DoShutdown never got set, the 10-minute timer "worked" once (set
DashcamShutdown=True) and then thermald died silently. Device kept
draining the battery instead of powering down.
Caught because CLAUDE.md specifically flags this pattern as a common
source of silent failures between C++ and Python.
