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

+Deploy Async Context Compression Filter Plugin
+
+Fast deployment script specifically for async_context_compression Filter plugin.
+This is a shortcut for: python deploy_filter.py async-context-compression

+Usage:
+    python deploy_async_context_compression.py
+
+To get started:
+    1. Create .env file with your OpenWebUI API key:
+       echo "api_key=sk-your-key-here" > .env
+    
+    2. Make sure OpenWebUI is running on localhost:3003
+    
+    3. Run this script:
+       python deploy_async_context_compression.py
