Add optional boot ROM emulation. When a boot ROM image is loaded, gb_reset
starts execution at PC=0 with power-on register state instead of the
documented post-boot state; the ROM overlays low memory (with the CGB
0x0100-0x01FF header hole showing the cartridge through) until the game
writes 0xFF50 to hand off. gb_load_bootrom() accepts 256-byte (DMG) or
2304-byte (CGB) images.

--keys "udlrabse." plays scripted joypad taps (each char = one button
held 10 frames then released 10, so the guest sees a clean edge); pairs
with --headless --shot to drive on-screen input and capture the result.
When --keys is active, serial-RX EOF stays pending instead of sending
$04, so a shell blocked on read waits for OSK input instead of exiting.

read()==0 completes the external-clock transfer with SB=0x04 (EOT), so a gbos
program's readc() sees EOF instead of polling forever. Enables cat/wc-style
tools and lets the shell exit on Ctrl-D / pipe end.

- external-clock transfers (SC=$80) deliver a stdin byte into SB without
echoing to stdout, and stay pending when no input is available -> programs
can poll for input cleanly. internal-clock (SC=$81) stays pure TX.

- --headless: no rendering/TUI; serial TX -> stdout, RX <- stdin (nonblocking)
- generalize serial: serial_out_fd/serial_in_fd on the GB; internal-clock
transfer now shifts in a real RX byte (from stdin) instead of always 0xFF
- paced to native speed by default, --uncapped for turbo; pipes/scripts cleanly
- README: document headless serial console

The APU was a black hole: reads returned 0xFF, writes were dropped. That hangs
any game that fades music out by decrementing the NR50/rAUDVOL volume register
until it reads 0 (Pokemon's StopMusic spin-wait) - the write never stuck, the
read never hit 0, infinite loop. Store the 48 sound registers and return them
with the standard hardware read-back OR-masks (NR50 mask 0x00 = exact readback).
No synthesis, just correct register behavior.

Passes blargg cpu_instrs (all 11), instr_timing, mem_timing.
