Changelog

[0.1.0] - 2026-05-18

Initial extract from harder-labs/vendure-platform (Phase 0 tasks #7, #14, #19).
PrintfulPlugin with idempotent submission, raw-body HMAC webhook, dedupe, sync record cache, admin retry mutation.
Custom fields on ProductVariant, Channel, Fulfillment.
Stub/live API client toggle via apiToken option.
Lease-based atomic claim on PrintfulSubmissionState and PrintfulWebhookDedupe (claimToken column scopes terminal updates).
Webhook error taxonomy: 401 on HMAC failure, 400 on JSON/schema failure.
BullMQ queue ownership lives in PrintfulOrderService so admin retries preserve the deterministic jobId guardrail.
TypeORM timestamptz on time columns (avoids TZ-naive comparison hazard).
