Implement Go-based test runner framework for Tesla K80 testing

Add comprehensive test orchestration framework:

Test Runner (cmd/test-runner/):
- config.go: YAML configuration loading and validation
- server.go: Ollama server lifecycle management (start/stop/health checks)
- monitor.go: Real-time log monitoring with pattern matching
- test.go: Model testing via Ollama API (pull, chat, validation)
- validate.go: Test result validation (GPU usage, response quality, log analysis)
- report.go: Structured reporting (JSON and Markdown formats)
- main.go: CLI interface with run/validate/list commands

Test Configurations (test/config/):
- models.yaml: Full test suite with quick/full/stress profiles
- quick.yaml: Fast smoke test with gemma2:2b

Updated Workflow:
- tesla-k80-tests.yml: Use test-runner instead of shell scripts
- Run quick tests first, then full tests if passing
- Generate structured JSON reports for pass/fail checking
- Upload test results as artifacts

Features:
- Multi-model testing with configurable profiles
- API-based testing (not CLI commands)
- Real-time log monitoring for GPU events and errors
- Automatic validation of GPU loading and response quality
- Structured JSON and Markdown reports
- Graceful server lifecycle management
- Interrupt handling (Ctrl+C cleanup)

Addresses limitations of shell-based testing by providing:
- Better error handling and reporting
- Programmatic test orchestration
- Reusable test framework
- Clear pass/fail criteria
- Detailed test metrics and timing

-
-          Verify that:
-          1. The model loaded successfully without errors
-          2. CUDA/GPU acceleration was properly detected and initialized
-          3. The model is using the Tesla K80 GPU (not CPU fallback)
-          4. There are no CUDA compatibility warnings or errors
-          5. Memory allocation was successful
-          6. Inference completed without errors
-
-          Respond with:
-          - "PASS" if all checks pass and model loaded properly with GPU acceleration
-          - "FAIL: <reason>" if there are critical issues
-          - "WARN: <reason>" if there are warnings but model works
-
-          Be specific about what succeeded or failed. Look for CUDA errors, memory issues, or CPU fallback warnings.
