refactor: promote new architecture to repository root

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.

- * .init_array, the VMM mapping code walks .text vs .rodata, ...)

- * Mirrors Linux arch/riscv/include/asm/sections.h / asm-generic/sections.h.
- * Each name and pair is identical to Linux so that direct ports of mm/init.c
- * relocate_kernel logic compile unchanged against LumeOS.
