Adds an SSH terminal plugin for KRDC that embeds KonsolePart
(Konsole's KPart terminal emulator) inside a RemoteView subclass.
The plugin registers the ssh:// URL scheme and launches ssh via
the TerminalInterface::startProgram() API.
Components:
- SshViewFactory: plugin factory handling ssh:// URLs
- SshView: RemoteView subclass embedding KonsolePart
- SshHostPreferences: configuration for username, identity file,
X11/agent forwarding, compression, and port forwarding tunnels
Key implementation details:
- KonsolePart loaded via KPluginFactory from kf6/parts/konsolepart
- ssh binary resolved via QStandardPaths::findExecutable()
- scaleResize() unconditionally calls resize() (KRDC's scroll area
does not use setWidgetResizable, relies on this slot)
- deleteLater() for KonsolePart teardown to avoid use-after-free
Build: standalone CMake project linking against krdccore and KF6::Parts.
