Initial implementation of govulncheck GitHub Action
This action runs govulncheck on Go projects and creates GitHub annotations
for vulnerabilities found in dependencies and code paths.

Features:
- Automated vulnerability scanning with govulncheck
- Smart annotations on go.mod for vulnerable dependencies
- Annotations on source code lines that call vulnerable functions
- Configurable working directory
- Output variables for vulnerability detection

The implementation includes:
- Modular architecture with separate concerns (execution, parsing, annotation)
- Comprehensive test suite with 100% function coverage
- Example vulnerable Go module for demonstration
- GitHub workflow example
- Full documentation
