bunny-subscriptions

Manage subscription lifecycle in Bunny. Covers the state machine (PENDING → ACTIVE → CANCELED / EXPIRED / TRIAL / TRIAL_EXPIRED), direct creation via subscriptionCreate vs quote-based creation, the nightly cron driving automated renewals / expirations / trial transitions, the evergreen auto-renew gate, explicit lifecycle mutations (subscriptionCancel, subscriptionReinstate, subscriptionSetAutoRenew, subscriptionTrialExtend, subscriptionTrialConvert), quantity updates (subscriptionQuantityUpdate), tenant metadata (subscriptionTenantUpdate), metered-usage reporting with featureUsageCreate / featureUsageUpdate / featureUsageDelete (requires billing:write), add-on co-renewal rules, price-adjustment timing on renewal, and when to reach for a quote (bunny-quoting) vs a direct mutation. Use when creating, modifying, renewing, or cancelling subscriptions; when reporting metered usage; or when orchestrating trial conversions.
