Module queue 

Per-session command queue with lane-based priority scheduling

Provides session-isolated command queues where each session has its own set of lanes with configurable concurrency limits and priorities.

External Task Handling

Supports pluggable task handlers allowing SDK users to implement custom processing logic for different lanes:

• Internal: Default, tasks executed within the runtime
• External: Tasks sent to SDK, wait for callback completion
• Hybrid: Internal execution with external notification

Implementation

The actual queue implementation is in SessionLaneQueue which is backed by a3s-lane with features like DLQ, metrics, retry policies, and rate limiting.
