Fix web terminal issues: improve xterm.js configuration, fix PTY setup, and resolve output alignment

- Enhanced xterm.js terminal configuration with proper theme, cursor, and font settings
- Fixed PTY setup in wssshd.py for better subprocess connection
- Improved terminal output formatting and line ending handling
- Resolved terminal connection and data flow issues
- Added proper terminal size configuration (80x24)
- Simplified input handling for better SSH compatibility

Add wssshc_watcher.sh script for monitoring and restarting wssshc with command-line arguments support

Add SSH options -o UserKnownHostsFile=/dev/null and -o LogLevel ERROR to all wsssh and wsscp implementations

Update README and CHANGELOG with latest improvements; enhance logo assets and C implementations; add clean script; update .gitignore to ignore videos

Resolve remaining compilation warnings in wssshc.c by fixing printf format specifier and type casts for size_t

Fix large WebSocket frame truncation in wssshc by reducing BUFFER_SIZE to 4096 to prevent partial reception on server

- Implement ping/pong event handlers in wsscp.py and wsssh.py
- Register ping_handler and pong_handler functions for WebSocket connections
- Enable debug logging for ping/pong events when debug mode is enabled
- Maintain automatic pong responses via websockets library while adding explicit handling

- Implement explicit ping/pong frame parsing and response in wsssh.c
- Add send_pong_frame function to handle WebSocket ping frames
- Maintain WebSocket protocol compliance for connection keep-alive
- Python implementations handle ping/pong automatically via websockets library

- Replace blocking recv() with select() for efficient I/O multiplexing
- Add 50ms timeouts to prevent indefinite blocking operations
- Increase buffer size from 4KB to 1MB for optimal throughput
- Add 3-second exit delay after SSH completion for clean shutdown
- Fix setup_tunnel return codes to prevent segmentation faults
- Correct memory management in argument cleanup

- Replace busy-waiting usleep loops with select() for efficient I/O multiplexing
- Add 50ms timeouts to prevent blocking operations
- Maintain 1MB buffers for optimal throughput
- Add 3-second exit delay after SCP completion for clean shutdown
- Fix critical bug in setup_tunnel return codes to prevent segfaults
- Correct memory management in argument cleanup to avoid corruption
- Add StrictHostKeyChecking=no option to wsscp and wsssh in both Python and C implementations

- Regenerated logo variants from source image
- Updated banner and icon files for consistency

- Fixed wssshd examples to include required --password parameter
- Updated wsssh examples to remove obsolete 'ssh' command requirement
- Updated wsscp examples to remove obsolete 'scp' command requirement
- Fixed debug mode examples to use current CLI syntax

- Fixed obsolete command line examples that were missing the required --password parameter
- Updated all wssshc usage examples in both files

- Added entry for GPL-3.0 license headers in shell scripts and C implementations
- Updated version 1.1.0 'Changed' section

- Added license headers to build.sh, clean.sh, and wssshtools/configure.sh
- Added license headers to wssshtools/wsscp.c, wssshtools/wsssh.c, and wssshtools/wssshc.c
- Headers match the format used in Python files for consistency

- Move C building logic outside Python-building conditional block
- Ensure --wssshtools-only builds all C tools (wssshc, wsssh, wsscp)
- Skip Python binary building when --wssshtools-only is specified
- Maintain compatibility with other build options

- Fix critical WebSocket frame parsing bug: signed char causing negative payload lengths
- Add comprehensive message type handling for tunnel_response, tunnel_request, tunnel_ack
- Implement buffered data transmission to prevent data loss from blocking sends
- Add frame processing safeguards to prevent infinite loops
- Optimize performance with increased sleep times to reduce CPU usage
- Clean up inappropriate debug output from utility functions
- Add proper resource management and error handling throughout

Root causes fixed:
1. Signed/unsigned char bug in frame length calculation
2. Missing tunnel_response message handling breaking SSH protocol
3. Data loss from non-blocking socket operations
4. Infinite loops from malformed frame processing
5. High CPU usage from short sleep intervals

The C implementation now properly handles WebSocket frames of all sizes and maintains SSH protocol data integrity.

- Added removal of wsssh-tools*.buildinfo files from both dist/ and root directories
- .buildinfo files are generated by dpkg-buildpackage for reproducible build information
- Ensures complete cleanup of all Debian packaging artifacts including build metadata

- Added cleanup for dist/ directory Debian files (moved by build.sh)
- Added cleanup for root directory Debian files (fallback)
- Added cleanup for wssshtools/debian/ build artifacts:
  - debian/wsssh-tools/ build directory
  - debian/files
  - debian/*.debhelper* files
  - debian/*.substvars files
  - debian/debhelper-build-stamp
- Ensures complete cleanup of all Debian packaging artifacts
- Maintains existing cleanup for PyInstaller and C build artifacts
