Version mismatch with VCS reference

The package declares version = "4.3.0" but uses a VCS reference to a feature branch (jw/SNOW-3230072-fix-missed-file-permission-check-skipping) instead of an actual 4.3.0 release tag. This creates several issues:

1. Misleading version: If snowflake-connector-python 4.3.0 is not yet released or this branch is not actually version 4.3.0, dependency resolution will fail or behave unexpectedly
2. No binary wheels: Unlike version 3.18.0 which had pre-built wheels for multiple platforms, this VCS reference has no wheels, forcing compilation from source on all platforms which will significantly slow installation and may fail on systems without build tools
3. Release notes inconsistency: RELEASE-NOTES.md claims version 4.3.0 is being used, but the actual dependency is an unreleased branch

Fix: Either:

# Use actual released version with wheels
version = "4.3.0"
sdist = { url = "https://files.pythonhosted.org/packages/...", ... }
wheels = [...]  # Include platform-specific wheels

Or if a pre-release is required:

# Use proper pre-release versioning
version = "4.3.0-dev+3064890"
vcs = { ... }
