Module context 

Context management patterns

This module provides thread-safe context management for WASM and native environments. Contexts are used to propagate information across function calls without explicit parameter passing.

Key Features

• Thread-Local Context: WASM-compatible thread-local storage
• Scoped Context: Automatic context cleanup with RAII
• Context Inheritance: Child contexts inherit from parent contexts
• Type Safety: Strongly typed context values
• Performance: Zero-cost abstractions with compile-time optimization

Structs

HashMapContext

Simple hash map based context manager

ThreadLocalContext

Thread-local context storage

Traits

ContextManager

Context manager trait for different context implementations
