feat(logging): add Pino logger implementation with Noop fallback

[Coderrob]

• Implemented NoopLogger class for silent logging when Pino initialization fails.
• Created PinoLogger class that utilizes Pino for structured logging.
• Added types for Pino logger configuration and metadata.
• Updated logging types to include new logger interfaces and metadata structures.

refactor(services): remove unused BarrelContentBuilder and FileSystemService

• Deleted BarrelContentBuilder and FileSystemService classes as they are no longer needed.

test(logging): add unit tests for BarrelContentBuilder and BarrelFileGenerator

• Created tests for BarrelContentBuilder to validate export generation.
• Added tests for BarrelFileGenerator to ensure correct barrel file creation and updates.
• Implemented tests for ExportParser to verify export extraction functionality.

chore(tests): update test configurations and improve test structure

• Refactored test runner to use fileURLToPath for path resolution.
• Created separate tsconfig.test.json for test-specific TypeScript configurations.
• Updated webpack configuration for better module resolution and source mapping.

chore(env): define environment variables interface for testing

• Added IEnvironmentVariables interface to standardize environment variable usage.

Pull Request Overview

This PR introduces a structured logging system with a Pino-based implementation and a Noop fallback, refactors the barrel generation logic into a core module, adds comprehensive unit/integration tests, and updates build/test/linting configurations.

• Add Pino logger (with metrics, filters, composite, factory) and Noop fallback; provide config resolver and types
• Refactor barrel generation into src/core/services with recursive support and improved export parsing
• Expand tests (Jest + Mocha), and update build (webpack/rollup) and linting (ESLint flat config) setup
