feat(async-context-compression): release v1.4.0 with structure-aware grouping and session locking

- Introduced Atomic Message Grouping to prevent tool-calling corruption (Issue #56)
- Implemented Tail Boundary Alignment for deterministic context truncation
- Added per-chat asynchronous session locking to prevent duplicate background tasks
- Enhanced summarization traceability with message IDs and names
- Synchronized version and changelog across all documentation files
- Optimized release-prep skill to remove redundant H1 titles

Closes #56
