What's New

Context.get() Default Parameter Support

Added support for default values in Context.get() and MutableContext.get() methods, improving developer experience when handling optional data.

Usage:

from codeuchain import Context

ctx = Context({'name': 'Alice'})
name = ctx.get('name', 'Unknown')  # Returns 'Alice'
age = ctx.get('age', 0)            # Returns 0 (default)

Changes

• ✅ Added default parameter to Context.get()
• ✅ Added default parameter to MutableContext.get()
• ✅ Comprehensive test coverage for default behavior
• ✅ Updated .gitignore for Python build artifacts
• ✅ Security improvements for demo output

Fixes

• Closes #42
