Archive the deprecated implementation under lume-legacy, make the new kernel the default root-level build, and update repository entry points without changing kernel behavior.

Replace the compressed boot path with a relocatable higher-half RISC-V entry, expand memory and SMP support, and add the driver, TTY, VFS, exec, signal, syscall, initramfs, and self-test infrastructure needed for a bootable kernel checkpoint.

- Updated physical memory management (PMM) to utilize memblock for memory layout and frame allocation.
- Enhanced the virtual memory manager (VMM) to allocate the frame map from memblock, ensuring it starts at the correct virtual address without relocation.
- Improved frame allocation and deallocation functions to handle physical addresses more consistently.
- Adjusted the slab allocator to correctly convert between physical and virtual addresses.
- Refined page fault handling to ensure proper frame allocation and address translation.
- Streamlined the initialization process for PMM and VMM, ensuring a more robust setup of memory structures.
