feat: VoiletXterm - Qt5 terminal workspace for SSH, Telnet and serial
Terminal core (src/core, QtCore only, headless testable):
- VT100/xterm parser: CSI/OSC/DCS, SGR 256/truecolor, scroll regions,
insert/delete, DEC special graphics, alternate screen
- cell grid with 5000 line scrollback, CJK wide chars, combining marks
- xterm 256 color palette
Terminal widget (src/term):
- QPainter renderer with run batching, wide char clipping, cursor blink
- mouse selection (char/word/line), auto copy, middle click paste
- full key encoding: arrows + DECCKM, F1-F12, modifiers, ctrl/alt
- IME support via inputMethodEvent
Transports (src/session):
- SSH through the system OpenSSH client on a forkpty pseudo terminal,
so agent, ProxyJump, known_hosts and 2FA keep working
- Telnet with IAC negotiation (NAWS, ECHO, SGA)
- Serial via QSerialPort
UI (src/ui):
- tabbed main window, session dialog with saved profiles
- dark violet theme, CLI targets (user@host:port, telnet://, serial:)
Tests:
- tests/test_core: escape sequence and layout assertions
- tests/test_widget: offscreen render checks and key encoding
