feat(build): add Linux package support and streamline build config

- Add project name and specific binary configuration for https_proxy
- Configure DEB and RPM package generation via nfpms
- Include systemd service file and installation scripts
- Add config file deployment to /etc/https_proxy/
- Limit builds to Linux (amd64, arm64) to focus on target platform
- Add ldflags for binary optimization (-s -w)
- Remove boilerplate comments and simplify goreleaser config

This enables automated creation of distribution packages for Debian and
RedHat-based systems with proper systemd integration and configuration
management.
