rock 4299d96b2e feat: M8.2 Gateway Queue Adapter for SQS via api.riotpiao.com
- Unified QueueAdapter trait for concurrent dual-write operations
- GatewayQueueAdapter routes messages via api.riotpiao.com with X-Service: sqs header
- TokenProvider abstraction: StaticTokenProvider + AuthentikTokenProvider
- JWT bearer token support (from Authentik OAuth2)
- InMemoryQueueAdapter for testing
- Base64 encoding/decoding for SQS message bodies
- HTTP/REST integration (no direct gRPC complexity)
- 8 unit tests + comprehensive documentation
- Supports long-polling (ReceiveMessage), visibility timeout, DLQ

Uses standard SQS API patterns:
- SendMessage: Queue chunk for dual-write processing
- ReceiveMessage: Long-poll up to 10 messages, 20s wait
- DeleteMessage: Acknowledge on success
- ChangeMessageVisibility: Retry on failure
- SendToDLQ: After max retries

//! M8.2 — Unified Queue Adapter (SQS-compatible interface)
//!
//! Abstraction over external queue services (SQS, kmsvc, RabbitMQ, etc.)
//! Enables concurrent dual-write processing without database overhead.
//!
//! # Design
//!
//! Rather than storing queue state in the database, we leverage external queue
//! services via a unified API. This enables true horizontal scalability:
//!
//! ```text
//! Ingest Worker Queue Service (SQS/kmsvc) Dual-Write Workers
//! │ │ │
//! │─── send_chunk() ────────────>│ │
//! │ │ │
//! └──────────────────────────────┤<─── receive_chunks(10) ────────┤
//! │ │
//! │<─── delete_chunk() ────────────┤
//! │ (on success) │
//! │ │
//! │<─── change_visibility() ───────┤
//! │ (on retry) │
//! ```
//!
//! # Implementations
//! - `SqsQueueAdapter`: AWS SQS backend
//! - `KmsvcQueueAdapter`: Kubernetes native messaging service
//! - In-memory for testing
