Issue: Implement Makefile for Development Automation

Problem Description

Following the standard patterns found in core Kubeflow repositories like pipelines and trainer, the docs-agent repository currently lacks a centralized automation tool for common development tasks.

Developers have to manually run various commands for:

• Building Docker images for the server.
• Compiling Kubeflow Pipelines.
• Running unit and E2E tests.
• Linting and formatting code.

This lack of automation increases the barrier for new contributors and leads to inconsistent development workflows.

Proposed Solution

Implement a root-level Makefile that provides a standardized interface for common tasks.

Target Commands to Implement:

• make build: Builds both the server and server-https Docker images.
• make compile: Compiles the pipelines/kubeflow-pipeline.py into a .yaml file.
• make test: Runs all tests (using pytest once standardized).
• make lint: Runs code quality checks (flake8, black, etc.).
• make clean: Removes temporary build artifacts and __pycache__ files.

Checklist

• Create a Makefile in the repository root.
• Implement build target for Docker images.
• Implement compile target for KFP components.
• Implement test and lint placeholders or targets.
• Document the use of make in the README.md development section.
