samakshkambxj/Origin-Kernel ? reverse-engineered prompt

Build me a custom Android kernel for Nothing phones with MediaTek chips, focused on good performance, stability, battery life, and a few extra power user features.

I want it to support the devices in this project, especially the CMF Phone 1, CMF Phone 2 Pro, and Nothing Phone 3a Lite, and make sure each build is device specific so nothing gets mixed up. Include root support with KernelSU style options, SUSFS support, Baseband Guard, better networking tweaks like BBR and IPv6 NAT, ZRAM with LZ4, and the other kernel tuning that helps the phone feel smoother without getting too risky. Keep it on Linux 6.1 and make the build flow clear enough that I can flash it safely.

If you need to check any current details, look up the latest docs online. Also add simple build and install instructions so someone like me can follow them without digging through kernel source.
