v0.6.2

Changed

• memory_state_add now accepts common state section aliases such as open_actions and current_focus, reducing friction when callers use descriptive names instead of short keys
• memory_state_add now accepts a single string for replace and treats it as a one-item pattern list, removing the need for callers to wrap simple replacements in an array
• Unknown state section key errors now include representative accepted keys and aliases, making recovery faster when a caller supplies an invalid section name
