*	Fix: critical malloc size calculation bug	Richard Qin	2026-01-03	1	-3/+0
\| \| \| \| \| \| \| \| \| \|	Summary: - Fixed an integer arithmetic error in malloc() where 'nunits' was initialized to 0, causing incorrect heap sizing. - This bug caused malloc to return pointers pointing to unmapped memory pages, leading to Store Page Fault (scause 15) at process boundaries. - Switched memory allocator logic to use byte-based size calculation instead of K&R style units to prevent off-by-one errors. Improvements: - Shell now starts successfully without segfaults.

	Introduce the foundational Physical Memory Manager (PMM) and restructure the project for modularity. Implemented basic PMM and related memory management headers (mm/pmm.h, mm/vm.h). Updated Makefile and build process to support new modular structure.
