fix: resolve critical security vulnerabilities in debug logging and command execution

- Remove sensitive data from debug logs (vault/secrets.go, secret/version.go)
- Add input validation for GPG key IDs and keychain item names
- Resolve GPG key IDs to full fingerprints before storing in metadata
- Add comprehensive test coverage for validation functions
- Add golangci-lint configuration with additional linters

Security improvements:
- Debug logs no longer expose decrypted secret values or private keys
- GPG and keychain commands now validate input to prevent injection attacks
- All validation uses precompiled regex patterns for performance
