Introduce a reflection-based config.Loader that populates config structs
from environment variables without requiring any external dependencies.
Naming convention: {PREFIX}_{STAGE}_{FIELD}
- Configurable prefix (default GOPIPE)
- Stage name uppercased and sanitized (hyphens/spaces → underscores)
- Field names converted from CamelCase to UPPER_SNAKE_CASE
- Named nested structs add their field name as a path segment
(e.g. EngineConfig.RouterPool.Workers → GOPIPE_ENGINE_ROUTER_POOL_WORKERS)
- Anonymous (embedded) structs are flattened
- Functions, interfaces, and other unsupported types are skipped
Supports: string, bool, int*, uint*, float*, time.Duration.
