v1.4.1

Release v1.4.1

This release fixes a critical SSH connection lifecycle bug, introduces ruff for code linting, and includes various code quality improvements.

Bug Fixes

• Fixed SSH connection double-close bug by centralizing lifecycle management in execute() instead of execute_command(), ensuring proper coordination between streaming and separate output modes.
• Fixed redundant logic in tab expansion for cleaner code execution.

Features

• Added ruff as code linter with import organization (isort compatibility) and Pyflakes rules for better code quality.
• Added scripts/lint-check-and-fix.sh for automated linting, import reorganization, and code fixing.

Enhancements

• Updated stream_command_output to use the LINES constant instead of hardcoded 1000 for better maintainability.
• Updated package dependencies for continued compatibility and security.

Code Quality

• Applied code formatting using black (v26.3.0) for improved consistency.
• Applied ruff linting with import sorting and Pyflakes rules across the codebase.
• Reorganized imports throughout the project for better consistency and PEP 8 compliance.
• Updated test files to follow consistent import ordering and structure.

Testing

• Updated 5 execute_command tests to verify connection close is not called (moved to execute()).
• Added 4 new tests for connection cleanup in execute() covering separate output, streaming, timeout handling, and already-closed connections.
• Fixed mock setup in async tests to avoid RuntimeWarning on async methods.
