ElfLoad read the entire binary into one kernel heap allocation before
copying segments out. The heap grows through ReallocConsecutive, so a
40 MB cc1plus required 10k physically contiguous pages - effectively
impossible after boot with a 368 MB ramdisk module resident, and the
failed spawn surfaced as posix_spawnp ENOENT in the gcc driver.
The loader now reads the ELF header and program header table (bounded
at 64 entries), then copies each PT_LOAD page and the PT_TLS template
directly from the VFS into freshly mapped process pages. Peak kernel
memory per load drops from fileSize to one page regardless of binary
size. Boot-smoke verified: all userspace loads through this path.
