Add wsscp - WebSocket SCP wrapper application

New wsscp application:
- WebSocket SCP wrapper similar to wsssh but for SCP instead of SSH
- Uses -P option for port detection (SCP standard) instead of -p
- Automatically constructs ProxyCommand for WebSocket tunnels
- Supports same command line syntax as regular SCP
- Includes automatic port detection from -P option
- Full integration with wsssht WebSocket tunnel infrastructure

Implementation details:
- wsscp.h: Header file with configuration structures and function declarations
- wsscp.c: Complete implementation with argument parsing and SCP command generation
- Updated configure.sh to build wsscp alongside other tools
- Added wsscp.1 man page with comprehensive documentation
- Tested functionality with debug mode and argument parsing

Features:
- Automatic wsssht path detection (PATH or same directory)
- Smart port detection: explicit --wssshd-port takes precedence over -P option
- Support for all wsssht tunnel options (--tunnel, --tunnel-control, --debug)
- Compatible with existing wssshc/wsssht infrastructure
- Proper error handling and user-friendly help messages

Usage examples:
  wsscp localfile user@myclient:/remote/path
  wsscp -P 2222 localfile user@myclient.server.com:/remote/path
  wsscp --debug --tunnel websocket localfile user@myclient:/remote/path

+.SH NAME
+wsscp \- SCP wrapper with WebSocket ProxyCommand support
+.SH SYNOPSIS
+.B wsscp
+[\fB\-\-help\fR] [\fB\-\-clientid\fR \fIclient_id\fR] [\fB\-\-wssshd\-host\fR \fIhost\fR]
+[\fB\-\-wssshd\-port\fR \fIport\fR] [\fB\-\-debug\fR] [\fB\-\-tunnel\fR \fItransport\fR]
+[\fB\-\-tunnel\-control\fR \fItransport\fR] \fIsource_file\fR \fIdestination\fR
+.SH DESCRIPTION
+.B wsscp
+is an SCP wrapper that automatically configures SCP to use WebSocket tunnels through
+.B wsssht
+with ProxyCommand. It parses the destination specification and constructs the appropriate
+SCP command with ProxyCommand to establish secure file transfers through WebSocket relays.
+.SH OPTIONS
+.TP
+.B \-\-help
+Show help message and exit.
+.TP
+.B \-\-clientid \fIclient_id\fR
+Specify the client ID of the registered wssshc endpoint.
+.TP
+.B \-\-wssshd\-host \fIhost\fR
+Specify the wssshd relay host.
+.TP
+.B \-\-wssshd\-port \fIport\fR
+Specify the wssshd relay websocket port (default: 9898).
+.TP
+.B \-\-debug
+Enable debug output. When debug is enabled, the SCP command is displayed but not executed.
+.TP
+.B \-\-tunnel \fItransport\fR
+Select data channel transport (comma-separated or 'any').
+.TP
+.B \-\-tunnel\-control \fItransport\fR
+Select control channel transport (comma-separated or 'any').
+.SH DESTINATION FORMAT
+The destination specification follows the format:
+.sp
+\fIuser\fR[\fB@\fR[\fIclientid\fR][\fB.\fR[\fIwssshd\-host\fR]][\fB:\fR[\fIremote_path\fR]]]
+.sp
+Where:
+.RS
+.TP
+\fIuser\fR
+SCP username
+.TP
+\fIclientid\fR
+Client ID of the registered wssshc endpoint
+.TP
+\fIwssshd\-host\fR
+wssshd relay hostname
+.TP
+\fIremote_path\fR
+Remote file path on the target system
+.RE
+.SH EXAMPLES
+.TP
+Copy file to myclient:
+.B wsscp localfile user@myclient:/remote/path
+.TP
+Copy file with specific relay host:
+.B wsscp localfile user@myclient.server.com:/remote/path
+.TP
+Copy file with custom port:
+.B wsscp -P 2222 localfile user@myclient.server.com:/remote/path
+.TP
+Enable debug output:
+.B wsscp \-\-debug localfile user@myclient.server.com:/remote/path
+.TP
+Specify transport:
+.B wsscp \-\-tunnel websocket localfile user@myclient.server.com:/remote/path
+.TP
+Pass additional SCP options:
+.B wsscp localfile user@myclient.server.com:/remote/path -P 2222 -o StrictHostKeyChecking=no
+.SH ENVIRONMENT
+.B wsscp
+requires
+.B wsssht
+to be available either in PATH or in the same directory as wsscp.
