10GlobalRateLimitedChatOpenAI(model: string, requestsPerSecond: number): Decorator for ChatOpenAI that enforces a global rate limit (requests per second) using a persistent SQLite table.
11GlobalRateLimiter: Class that implements the rate limiting logic. It checks the number of requests in the current time window and throws an error if the limit is exceeded. It uses a table (global_rate_limit_1) in Val Town's SQLite.
12ensureGlobalRateLimitTableExists: Ensures the rate limit tracking table exists in the database at startup.
13Usage
14Use ChatOpenAI(model) for direct, unlimited access to OpenAI chat completions.
