- rtc.rs: read the PC RTC via CMOS ports 0x70/0x71 (UIP wait, BCD/12h
normalization, century sanity-check with 2000+ fallback); boot prints
the wall clock, shell gains 'date'
- pci.rs: legacy config-space access (0xCF8/0xCFC) with full enumeration
of buses 0-255; boot reports device count, shell gains 'pci' (lspci
style listing with class names)
- QEMU q35 verified: Q35 host bridge, stdvga, e1000, ICH9 LPC

- uefi.rs: full EFI_RUNTIME_SERVICES layout with reset_system at index 10
(spec order); EfiResetSystem type + RESET_* constants
- power.rs: stash the runtime-services table pre-EBS; poweroff() calls
ResetSystem(EfiResetShutdown) — still callable after ExitBootServices
because we never call SetVirtualAddressMap, so the pointers keep
working with physical addresses; falls back to the hlt loop
- shell: 'poweroff' and 'exit' shut the machine down (QEMU exits),
'halt' keeps the plain hlt loop

- uefi.rs: full EfiMemoryType constants (0-14) + memory_type_name(); fix
MEMORY_TYPE_LOADER_DATA from 6 to 2 per the UEFI spec
- memory.rs: replace the bump allocator with a first-fit free-list heap
(splitting, coalescing, 8-byte back-pointer for alignment-safe free);
add a bitmap physical page allocator (heap region reserved, page-0
guard, aligned runs); grow the heap from the page allocator on demand
- paging.rs: identity page-table helpers — adopt_tables() rebuilds the
firmware map into our own tables (OVMF maps its tables read-only, so
the firmware tree can't be modified in place) and switches CR3;
map_page/unmap_page/is_mapped with 2 MB/1 GB large-page splitting
- main.rs: boot self-tests for heap, pages, and paging

Architecture:
rs-dos/ (workspace root, was raisernics/)
├── rsnix/ — kernel lib crate (uefi, serial, gop, ps2, interrupts, memory)
├── shell/ — shell lib crate (prompt, commands, line input)
├── rsdos/ — binary crate (efi_main, init, panic handler)
└── rsboot/ — future git submodule
No functional changes — boots to shell prompt identically.
Version auto-pulled from Cargo.toml via env!("CARGO_PKG_VERSION").
