TMNL Registry Patterns

Canonical patterns for creating and using singleton registries in TMNL, with emphasis on effect-atom integration.

Overview

Registries provide centralized state management and lookup services for:

• Overlay system state (overlayRegistry)
• Token-based registries (binding sources, scopes)
• Kernel registries (data-manager drivers)
• Command registries (command execution and keybindings)

Key Distinction: Registry subscription (registry.subscribe()) vs. atom consumption (useAtomValue()).
