Add CI/CD pipeline, logging enhancements, and release management

- Create a GitHub Actions workflow for testing with Python 3.12 and 3.13.
- Update Makefile to include release management commands and pipeline checks.
- Document the CI/CD pipeline structure and usage in PIPELINE.md.
- Add structlog for structured logging and enhance logging utilities.
- Implement release management script for automated versioning and tagging.
- Modify logging configuration to support structured logging and improved formatting.
- Update dependencies in pyproject.toml and poetry.lock to include structlog.
- Enhance access logging in server and middleware to include structured data.

+# Automated Release Configuration
+
+## How to use the pipeline
+
+### 1. Linting (executed on every push)
+```bash
+# Triggers:
+- push to any branch
+- pull request to any branch
+
+# Checks:
+- Black (code formatting)
+- isort (import sorting)
+- flake8 (linting)
+- mypy (type checking)
+```
+
+### 2. Tests (executed for dev, master, main)
+```bash
+# Triggers:
+- push to branches: dev, master, main
+- pull request to branches: dev, master, main
+
+# Checks:
+- pytest on Python 3.12 and 3.13
+- coverage reports
+```
+
+### 3. Build and release (executed for tags)
+```bash
+# Triggers:
+- push tag matching v*.*.*
+- manual dispatch through Gitea interface
+
+# Actions:
+- Package build via Poetry
+- Draft release creation
+- Artifact upload (.whl and .tar.gz)
+```
+
+## Release workflow
+
+1. **Release preparation:**
+   ```bash
+   # Update version in pyproject.toml
+   poetry version patch  # or minor/major
+   
+   # Commit changes
+   git add pyproject.toml
+   git commit -m "bump version to $(poetry version -s)"
+   ```
+
+2. **Tag creation:**
+   ```bash
+   # Create tag
+   git tag v$(poetry version -s)
+   git push origin v$(poetry version -s)
+   ```
+
+3. **Automatic process:**
+   - Pipeline starts automatically
+   - Linting and tests execute
+   - Package builds
+   - Draft release created
+
+4. **Release finalization:**
+   - Go to Gitea interface
+   - Find created draft release
+   - Edit description according to template
+   - Publish release
+
+## Environment variables
+
+For correct pipeline operation, ensure:
+- `GITHUB_TOKEN` - for release creation
+- Repository permissions for release creation
+
+## Customization
+
+- Change Python versions in `test.yaml` if needed
+- Add additional checks in `lint.yaml`
+- Configure notifications in `pipeline.yaml`
