- Line 19: Validate redis_fetch_batch_size at assignment time by adding or
updating its setter near the configuration initialization and update flow.
Require a positive Integer, raise ConfigurationError with the established
setting name for invalid values, and delegate valid values through the
superclass setter so invalid batch sizes cannot reach notification claiming.

Reject invalid Redis fetch batch sizes before claiming notifications.
redis_fetch_batch_size = 0 reaches find_notifications_by_ids, where each_slice(0) raises. Redis has already removed the claimed pending or retryable IDs, and the feeder only logs the exception. Those notifications can remain undelivered and absent from both claim sets.

Adds aggregate feeder/Redis claim telemetry and a sandbox-only RPUSH_SIMULATE_DELIVERY=true path before provider dispatch. Simulated outcomes persist terminal Redis state but emit notifications_simulated, not notification_delivered. The switch is inert outside RAILS_ENV=sandbox. Intended for a bounded claim/processing benchmark, not evidence of APNs/FCM accepted-send capacity. Unit specs and a local dependency-free behavior check cover single and batch paths; the full fork suite is blocked locally by old pg/native dependencies on available Ruby.
