*	feat: Add initial Supervisor Mode Trap Handler	Richard Qin	2025-12-10	12	-17/+310
\| \| \| \| \| \| \| \| \| \|	Implement the initial mechanism for handling traps and exceptions in Supervisor Mode. Set up the stvec Control and Status Register (CSR) to direct all S-Mode Traps (Interrupts and Exceptions) to a unified assembly entry point. Implemented assembly code for saving and restoring the Trap Context (register state). Provides the foundational framework necessary for future Timer Interrupts and System Calls.
