syscall: mirror console output to the LCD terminal
KPutc's console path now renders each byte on the LCD terminal via
term_putc in addition to the serial write. Serial is kept so scripted
tests still capture output (and for link-cable/debug), while the shell,
command output, and echoed input now appear on-screen in the 40-col font
with a live cursor and scrolling. Dropped the boot-time term_demo; the
terminal starts blank and fills from real console traffic.
term_putc now saves/forces/restores SVBK=1 so it always reads and writes
the terminal buffer/state in WRAM bank 1, regardless of which process
context KPutc is invoked from (defensive; all procs currently use bank 1).
The stack lives in non-banked WRAM, so saving SVBK across the switch is safe.
Verified: a headless run of `uname; ls; echo hello world` renders each
prompt, the echoed command, and its output on the LCD (captured via the
new `--headless --shot` path), and serial capture is unchanged.
