Pull Request Overview

This PR fixes versioning in wheel distributions by enabling version information to persist when Git is unavailable. The changes ensure that VERSION.txt is created during distribution and can be read when building from an sdist package.

• Adds fallback to read version from VERSION.txt file when Git repository is unavailable
• Creates VERSION.txt in distribution packages via meson dist script
• Ensures output directory exists before writing VERSION.txt

The VERSION.txt path is hardcoded relative to the script location, but the meson.build script writes it to scripts/versioning/VERSION.txt relative to MESON_DIST_ROOT. This path mismatch will cause the fallback to fail when the script is executed from different locations or in installed packages.

Suggested change

	script_dir = os.path.dirname(os.path.abspath(__file__))
	version_file = os.path.join(script_dir, 'VERSION.txt')
	version_file = os.path.join('scripts', 'versioning', 'VERSION.txt')

The bare except Exception silently swallows all errors including IOError, PermissionError, and UnicodeDecodeError. This makes debugging difficult if the VERSION.txt file exists but cannot be read. Consider catching specific exceptions or logging the error.

Suggested change

	except Exception:
	pass
	except (OSError, IOError, PermissionError, UnicodeDecodeError) as e:
	print(f"Error reading VERSION.txt: {e}", file=sys.stderr)
