Added Files:

Modified Files:

Log Message:
Add Atari ST VT52 documentation and cterm unit test harness

Document the Atari ST VT52 emulation mode in cterm.adoc: C0 controls,
standard VT52 sequences, GEMDOS/TOS extensions, color palettes for
all three screen modes (40x25/16-color, 80x25/4-color, 80x25/mono),
reverse video behavior, and differences from standard VT52.

Add cterm_test  a unit test framework for non-ANSI emulation modes.
Uses SDL offscreen backend with direct cterm_init/cterm_write/
vmem_gettext calls, no PTY or syncterm process needed. 38 VT52 tests
covering: printable chars, C0 controls (CR/LF/BS/BEL/HT/VT/FF),
cursor movement (up/down/left/right/home), direct addressing (ESC Y),
screen clearing (ESC E/J/K/d/l/o), line editing (ESC L/M), cursor
save/restore, show/hide cursor, reverse video, autowrap on/off,
color setting, keypad modes, scrolling, and line wrapping.
