subscription-mollie

Mollie payment provider plugin for billing-foundation, covering the DACH/EU mid-market use case. Mount via createSubscriptionMollieFeature({ apiKey, webhookUrl, priceToTier, priceToConfig }) — the factory validates that priceToTier and priceToConfig keys are identical at boot time. Implements verifyAndParseWebhook (lazy Mollie-API fetch + heuristic event-type mapping) and createCheckoutSession (customer + first-payment with sequenceType="first"); createPortalSession and cancelSubscription are not available because Mollie has no customer portal and requires a customerId that the plugin contract does not carry.
