feat: Add wsssht - WebSocket SSH Tunnel tool

- Create wsssht.c: Stripped-down tunnel setup tool (like wsssh --dev-tunnel)
- Add separate wssht.conf configuration file support
- Implement read_config_value_from_file() for custom config files
- Create wssht.conf.example with tunnel configuration options
- Update wsssht.1 man page with separate config file documentation
- Add wsssht to build system (configure.sh, Makefile)
- Test successful compilation and functionality

wsssht provides manual tunnel setup without auto-executing SSH/SCP,
displaying connection information for telnet, nc, or any TCP client.

+.SH DESCRIPTION
+.B wsssht
+is a WebSocket SSH tunnel setup tool that establishes secure tunnels through WebSocket connections without automatically executing SSH/SCP commands. It provides connection information for manual use with any TCP client.
+.PP
+Unlike
+.BR wsssh (1)
+and
+.BR wsscp (1),
+.B wsssht
+does not fork and execute external commands. Instead, it sets up the tunnel and displays connection instructions for manual use.
+.SH OPTIONS
+.TP
+.BR \-\-local\-port " \fIPORT\fR"
+Specify the local port for the tunnel (default: auto\-assigned)
+.TP
+.BR \-\-interval " \fISEC\fR"
+Connection retry interval in seconds (default: 30)
+.TP
+.BR \-\-debug
+Enable debug output
+.TP
+.BR \-\-tunnel " \fITYPES\fR"
+Transport types for data channel (comma\-separated or 'any', default: any)
+.TP
+.BR \-\-tunnel\-control " \fITYPES\fR"
+Transport types for control channel (comma\-separated or 'any', default: any)
+.TP
+.BR \-\-service " \fISERVICE\fR"
+Service type (default: ssh)
+.TP
+.BR \-\-help
+Display help message and exit
+.TP
+.BR \-p ", " \-\-port " \fIPORT\fR"
+WebSocket SSH daemon server port (default: 9898)
+.SH EXAMPLES
+.TP
+Basic tunnel setup:
+.B wsssht user@myclient.example.com
+.TP
+Specify local port:
+.B wsssht \-\-local\-port 2222 user@myclient.example.com
+.TP
+Use specific transport:
+.B wsssht \-\-tunnel websocket user@myclient.example.com
+.TP
+Debug mode:
+.B wsssht \-\-debug user@myclient.example.com
+.SH MANUAL CONNECTION
+Once the tunnel is established,
+.B wsssht
+displays connection information:
+.PP
+.RS
+.nf
+========================================
+        WEBSSH TUNNEL READY
+========================================
+Tunnel established successfully!
+Local port: 49234
+Target: user@myclient.example.com
+
+Connect manually using one of these commands:
+
+  Telnet:
+    telnet localhost 49234
+
+  Netcat:
+    nc localhost 49234
+
+  SSH (if connecting to SSH server):
+    ssh -p 49234 user@localhost
+
+  SCP (if connecting to SSH server):
+    scp -P 49234 user@localhost:/remote/path ./local/path
+
+  Any TCP client:
+    Connect to localhost:49234
+
+Press Ctrl+C to close the tunnel and exit.
+========================================

+.SH CONFIGURATION
+.B wsssht
+supports a separate configuration file at
+.I ~/.config/wsssh/wssht.conf
+with the following options:
+.PP
+.RS
+.nf
+[default]
+port=9898
+domain=example.com
+tunnel=websocket
+tunnel-control=websocket
+service=ssh
+interval=30
+.fi
+.RE
+.PP
+Note: Unlike
+.BR wsssh (1)
+and
+.BR wsscp (1),
+.B wsssht
+uses its own configuration file
+.I wssht.conf
+instead of sharing
+.I wsssh.conf.
