Modify nvfancontrol Fan Profile (BSP-side)

Purpose

Edit the per-board nvfancontrol configuration so the device boots with the desired fan curve / control mode / governor / default profile. BSP-side only — all writes land in the overlay tracker, the upstream bsp_image copy is read-only.

This skill handles BSP-side edits to the per-board nvfancontrol configuration file: adding profiles, removing profiles, editing the temp → PWM / RPM curves, changing the boot default profile / control mode / governor, and listing defined profiles. Applies on Jetson / Tegra platforms (T234 Orin, T264 Thor).
