Subject: kernel: dmesg-style boot spew before init spawns

Print everything the kernel knows implicitly at boot, Linux-flavored, on
the LCD console and mirrored over the link (gbhub logs each GB's boot):

  gbos sm83 microkernel
  console: CGB (boot a=$11)          <- boot ROM's A/B, saved at entry
  cart: mbc5, 1M rom, 128K sram      <- our own cart header ($0147-49)
  mem: 32K wram 16K vram 127B hram   <- CGB constants
  proc: 8 slots, 31 programs         <- link-time table sizes
  net: slip on link port, 4 sockets
  fs: gbfs v3 mounted, 120/128 blk free  <- bitmap popcount; 'formatted'
  tty: 40x18 console, SELECT = osk      on first boot
  init: spawning pid 1

New src/dmesg.asm with kernel print helpers (kputc/kputs/kputhex/kputdec)
that bypass KPutc (no process context at boot). term_init now runs before
net/fs init so the spew is visible as subsystems come up.
