- ps2: Ctrl+C and Ctrl+D are now KeyEvents (ctrl modifier + c/d map);
other Ctrl+key combos are swallowed
- shell read_line: ^C clears the line and echoes '^C' (bash-style),
^D on an empty line echoes '^D' and shuts down (EOF), ^D with text
on the line is ignored
- cat/hexdump stream incrementally (was: build whole string then print)
and check for ^C between chunks, so a running dump can be aborted
- verified in QEMU: line cancel, standalone interrupt, ^C aborts an
infinite 'cat /dev/zero' stream, ^D powers off

- fs.rs: node-table VFS (root /dev /tmp /etc). Regular files are
in-memory ramfs; char devices regenerate content on every read so
'cat /dev/rtc' shows the live time. Nodes are stable handles with
tombstone removal; . and .. path resolution.
- /dev devices: mem (raw physical RAM, offset = address), rtc, pci,
version, meminfo, null, zero, console (write prints to screen+serial),
serial. /etc/motd static file.
- shell: ls, cat, hexdump (hexdump -C style), mkdir, touch, rm; echo
gains '>' overwrite and '>>' append redirection (append bug fixed:
first '>' in '>>' was parsed as overwrite)
- boot: fs init + self-test (create/read/write/remove) before the shell
- QEMU verified: file lifecycle, redirection, console/null writes,
mkdir/touch/rm, hexdump /dev/mem and /tmp/x byte-exact

- 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

- paging strategy: adopt_tables() rebuilds the firmware map into the
kernel's own tables (UEFI maps its tables read-only) and switches CR3
- physical memory: heap grows into the page allocator on demand
- milestones: paging helpers, heap growth, mmap/stress commands
- project layout: paging.rs entry
