kernel!: lots of changes, see commit details.
refactor(hal): unify file naming and drop redundant architecture suffixes feat(build): rename kernel and bootloader to 'ne_kernel' and 'ne_bootz' refactor(memory): replace mm_get_phys_address with mm_get_page_addr feat(bitmap): track bitmap allocator usage and add out-of-memory error fix(heap): correct heap magic naming and alignment logic chore(fs): downgrade HeFS disk size check to warning chore(tools): clean up formatting in 'ping' and 'manual' docs(design): update OS_DESIGN.drawio to reflect Hypr86 and new layout Signed-off-by: Amlal El Mahrouss <amlal@nekernel.org>
