Pharaoh2k 1a18f94eaf Add FS/GS base get/set commands and make GET/SETFPREGS YMM-aware ...

New per-thread segment-base access, HW-validated on FW 9.00 (read and write):
- 0xBDBB000E GET_FSGS_BASE: 16-byte {fs_base, gs_base} read from the pcb
- 0xBDBB000F SET_FSGS_BASE: writes fs/gs base into the pcb
  (pcb_fsbase @ pcb+0x40, pcb_gsbase @ pcb+0x48; kernel-path only, no ptrace)

GETFPREGS/SETFPREGS now read and write the full 832-byte xsave image via the
kernel pcb_save area (pcb+0x148) so the YMM (AVX) upper halves are populated
and applied, falling back to PT_GET/SETFPREGS for the 512-byte FXSAVE path.

SET handlers memset their buffer and bail on a short net_recv_all before
writing, so a malformed SET cannot push garbage into the pcb/xsave.

Docs: PROTOCOL.md (two command sections, table rows, YMM notes on GET/SETFPREGS,
corrected debug.c line refs, opcode count to 69) and README.md (register
capability line, namespace command counts).
