/**
* Method string constants for MCP Apps protocol messages.
*
* These constants provide a type-safe way to check message methods without
* accessing internal Zod schema properties. External libraries should use
* these constants instead of accessing `schema.shape.method._def.values[0]`.
*
* @example
* ```typescript
* import { SANDBOX_PROXY_READY_METHOD } from '@modelcontextprotocol/ext-apps';
*
* if (event.data.method === SANDBOX_PROXY_READY_METHOD) {
* // Handle sandbox proxy ready notification
* }
* ```
