docs(hardware): record working text-console login + driver coverage

Text login (getty -> brush) works on bare/mini after the relibc F_DUPFD_CLOEXEC
fix; document storage/USB/GOP bare-metal boot coverage and the outstanding
Intel 2.5GbE igc (I225/I226) and e1000e (I219) network driver gap for modern
Arrow Lake boards.

 This section contain limitations that apply to any status.
 
+- Text-mode console login is **working** on the `redbear-bare` and `redbear-mini`
+  targets: the boot reaches a `getty` login prompt (serial debug console and
+  framebuffer VT) and authenticates into the default shell **`brush`** (a
+  Rust-native shell; `zsh`/`ion` are no longer the default). This depends on a
+  relibc fix that translates the POSIX `F_DUPFD_CLOEXEC` fcntl command to the
+  Redox syscall ABI — without it `OwnedFd::try_clone()` returned EINVAL and every
+  `tokio` runtime (all zbus system daemons and the shell) failed to start.
+- Storage, USB and display bring-up cover the common modern-Intel (incl. Arrow
+  Lake) bare-metal boot path: NVMe (`nvmed`), AHCI/SATA (`ahcid`), USB 3 xHCI
+  (`xhcid`) with USB HID input, and UEFI GOP framebuffer (`vesad`). An empty
+  ATAPI/optical drive is now handled as a normal no-media state instead of
+  logging I/O errors.
+- Wired networking driver coverage is Intel `e1000` (`e1000d`), Intel 10G
+  (`ixgbed`), Realtek `rtl8139`/`rtl8168`, and `virtio-net`. **Intel 2.5 GbE
+  `igc` (I225/I226, common on modern Arrow Lake / Z890 boards) and `e1000e`
+  (I219) are not yet supported** — a machine relying solely on one of those has
+  no Ethernet until a driver is added. Text login is unaffected (it does not
+  require networking).
 - ACPI bring-up is **materially complete for boot baseline**; implemented: kernel
   RSDP/RSDT/XSDT/MADT/FADT coverage, AML mutexes with real tracked state, EC widened accesses via
   byte transactions, kstop-based shutdown eventing, explicit `RSDP_ADDR` forwarding into `acpid`,
