v0.1.1

Added

• Unit Tests: 94 new tests across auth, session, message, and webhook modules (110 total, ~17% coverage)
• Release Workflow: release.yml GitHub Actions — tag-triggered with test gate, GitHub Release, and Docker semver tagging
• SDK Scaffolds: JavaScript/TypeScript and Python client libraries in sdk/ directory
• New hook events: webhook:queued (after queue add) and webhook:delivered (after actual delivery)

Fixed

• [P1] Idempotency Key: Made generateIdempotencyKey deterministic by removing Date.now(). Keys are now content-based for proper deduplication
• [P2] Webhook Processor: Added lastTriggeredAt update and webhook:delivered/webhook:error hooks after queue delivery
• [P2] Hook Semantics: Added webhook:queued event for queue mode; webhook:after now only fires in direct mode
• [P2] QueueModule DI: Added TypeOrmModule.forFeature([Webhook]) and HooksModule imports for proper dependency injection
• [P3] Message Processor: Changed placeholder to throw error so BullMQ correctly marks job as failed
