BruxinCore/CalamityKernel-spacewar ? reverse-engineered prompt

Build me a custom Android kernel for the Nothing Phone 1 that focuses on speed, smooth touch response, better battery life, and stable daily use. I want it to stay close to the existing Nothing source, but with the performance tweaks and root support already described in the project, including the faster scheduler behavior, improved memory compression, better network latency, and the built in WireGuard support. Please make sure it still builds cleanly for the device and that the install process works with a boot image flash on both slots. If anything in the current kernel source needs to be adjusted to keep it stable on Android 13, 14, and 15, handle that too. Keep the changes practical and not bloated, and look up current docs online if you need to confirm anything important before you make changes.
