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.
