[Bugfix] Pull request for testing pyapplication deployment script

[lstein]

This pull request introduces several improvements to the build and deployment workflows for PyInstaller executables and macOS app bundles, focusing on better disk space management, more robust artifact packaging, and enhanced macOS support. It also removes the unused macos/setup.py script and updates the project version.

Workflow and Build Improvements

• Added disk space cleanup steps for all platforms in the PyInstaller workflow to prevent build failures due to insufficient space. (.github/workflows/deploy-pyinstaller.yml, INSTALL/pyinstaller/make_pyinstaller_image.sh, INSTALL/pyinstaller/make_pyinstaller_image.ps1) [1] [2] [3]
• Enhanced packaging logic: executables and app bundles are now conditionally renamed and zipped, supporting both file and directory outputs on all platforms. (.github/workflows/deploy-pyinstaller.yml)
• Added support for building a macOS .app bundle using a --macos-app flag in the PyInstaller build script, with corresponding workflow matrix changes and macOS-specific PyInstaller options. (INSTALL/pyinstaller/make_pyinstaller_image.sh, .github/workflows/deploy-pyinstaller.yml) [1] [2] [3]
• Removed the legacy and unused macos/setup.py script, consolidating macOS packaging under PyInstaller. (macos/setup.py)

Project Metadata

• Bumped the project version from 0.9.3 to 0.9.4 in pyproject.toml. (pyproject.toml)
