Stripe CLI trigger command does not support payout, invoice, and trial lifecycle events that developers need to test subscription billing flows

The `stripe trigger` command only supports a small subset of Stripe events. Critical billing lifecycle events that developers need to test locally -- payout.paid, customer.source.expiring, invoice.upcoming, and subscription trial period events -- are all marked as unsupported event types and cannot be triggered. This means developers building subscription billing flows, dunning logic, card-expiry retry systems, or payout reconciliation tools cannot test those paths locally without manually pushing test data through the dashboard. The pattern appears across at least four separate open issues totaling over 80 reactions and is labeled by Stripe as 'unsupported-event-type' with no planned ship date. A companion CLI or plugin that extends the Stripe CLI event catalog -- generating realistic payloads for these lifecycle events and forwarding them to the local listen endpoint -- would close a hole that Stripe has explicitly left open since 2019.
