Fix create-release workflow for new artifact structure

**Problem:** Artifact download extracts files directly to working directory, not into a subdirectory as expected.

**Analysis:** From failed run logs, all files are present:
- ✅ PyFlowGraph.exe (8.8MB)
- ✅ examples/ directory
- ✅ python_runtime/ directory
- ✅ All Qt DLLs and required components

**Root Cause:** GitHub Actions downloads artifacts by extracting contents directly, not preserving directory structure.

**Solution:**
- Remove expectation of subdirectory structure
- Check for files directly in working directory
- Verify PyFlowGraph.exe and key directories exist
- Create zip from current directory with exclusions
- Exclude development files (src/, tests/, .git/, docs/, etc.)
- Include only runtime files needed for distribution

**Result:** Release zip will contain clean distribution ready for end users.
