Add Go-based utility to replace hack/verify-steering-election.sh

- Create new Go utility with enhanced validation capabilities
- Validate YAML header format using gopkg.in/yaml.v3 library
- Check filename format matches GitHub ID in header
- Verify required template sections are present
- Support both regular steering and GB election formats
- Apply validation only to elections from 2025 forward
- Update shell script to invoke Go utility

Features:
- Proper YAML parsing instead of regex validation
- Unified validation logic for all election types
- Better error messages for malformed headers
- Type-safe validation of candidate bio structure
