Add CI pipeline using test-framework-template #2

Summary

Set up a CI pipeline for testlink-code by installing test-framework-template into the cicd/ directory. This gives us automated validation on PRs and pushes before we start adding new API endpoints (see #1).

Motivation

• No test coverage or linting exists today — only a Docker publish workflow
• Issue [feat] Add deleteTestCase and deleteTestSuite to XML-RPC API #1 will add deleteTestCase and deleteTestSuite endpoints — we need CI to validate those changes
• test-framework-template provides YAML-driven tests with GitHub Actions workflows ready to use

Plan

Install Framework

• Run make install from test-framework-template into cicd/
• Add test-pipeline.yml and test-suite.yml workflows to .github/workflows/
• Configure config.ts for testlink-code

Build Suite (TC-BUILD-*)

• PHP syntax check — find . -name '*.php' | xargs php -l
• Docker build — verify the image builds successfully
• Composer install — verify dependencies resolve

Integration Suite (TC-INTEGRATION-*)

• Container startup — docker compose up, health check
• XML-RPC API smoke test — call tl.ping, verify response
• Authentication — call tl.checkDevKey with test API key

E2E Suite (TC-E2E-*)

• Full CRUD workflow — create project → create suite → create test case → verify → cleanup
• Validates the API endpoints work end-to-end against a real TestLink instance

Dependencies

• Docker Compose setup for TestLink + database (may need a docker-compose.ci.yml)
• Node.js 20 for the test runner
• Ollama (optional, for LLM judge — can run with --no-llm in CI initially)

Acceptance Criteria

• cicd/ directory installed with test-framework-template
• GitHub Actions runs on PRs and pushes
• Build suite passes (PHP lint, Docker build)
• Integration suite passes (container starts, API responds)
• E2E suite passes (CRUD workflow)
