- Create wsssh.h header file with configuration structures and function declarations
- Implement wsssh.c with comprehensive SSH wrapper functionality:
  * Parse command line arguments (--help, --clientid, --wssshd-host, --wssshd-port, --debug, --tunnel, --tunnel-control)
  * Parse target string in format: user[@clientid[.wssshd-host[:sshstring]]]
  * Build ProxyCommand using wsssht --pipe with appropriate options
  * Find wsssht in PATH or same directory as wsssh
  * Construct and execute SSH command with ProxyCommand
  * Debug mode shows constructed command without executing
- Add wsssh to build system (configure.sh and Makefile)
- Update debian/control to include wsssh in package description
- Create comprehensive man page (man/wsssh.1) with usage examples
- Tested functionality with various command line options

wsssh provides a convenient wrapper around SSH that automatically sets up
WebSocket tunneling through wsssht, making it easy to use SSH with WebSocket
relays without manual ProxyCommand configuration.
