docs(#1): SDK integration guide, API reference, and CI pipeline

- Rewrite README with quick start, FastAPI snippet, async/sync patterns,
  config reference with env vars, and API version targeting (v1, schema 1.0)
- Add docs/integration-guide.md with full FastAPI and generic Python
  integration examples, environment-specific config, prediction queries,
  error handling, and dry-run mode documentation
- Add docs/api-reference.md covering all exported classes, methods, Pydantic
  models, enums (TaskType, Complexity, Harness, Provider, QualityGate,
  Outcome, RepoSizeCategory), and internal components
- Add Woodpecker CI pipeline (.woodpecker.yml) with quality gates: lint,
  format check, typecheck, bandit security scan, pip-audit, and pytest
  with 85% coverage gate
- Add bandit and pip-audit to dev dependencies

Fixes #1
