Event batching and delivery

Both libraries buffer events and send them in batches via HTTP POST to the configured endpoint.

Parameters

Parameter	Value
Flush interval	2 seconds
Flush threshold	20 events
Transport	HTTP POST with JSON body
Auth header	`x-api-key: <apiKey>`
Error handling	All errors silently swallowed — never affects host app

Uses globalThis.fetch. The timer is unref’d so it doesn’t keep the process alive. Call shutdown() to flush remaining events and stop the timer.

Uses urllib.request (stdlib). The timer is a daemon thread. An atexit handler calls shutdown() automatically on process exit.
