Rumpk Stability, NipBox Boot, and Repository Cleanup

- Fixed Rumpk RISC-V Trap Handler (SSCRATCH swap, align(4), SUM bit) to prevent double faults.

- Stabilized Userland Transition (fence.i, MMU activation) allowing NipBox execution.

- Restored Forge pipeline to build NipBox from source.

- Documented critical RISC-V trap mechanics in .agent/tips.

- Committed pending repository cleanup (obsolete websites) and new core modules.
