## Summary
When running MCP service in Kubernetes with multiple replicas, session state
(SSE events, progress updates) needs to be shared across pods. This change adds
support for Redis-backed EventStore.
### Changes
- Added `MCP_EVENT_STORE_CONFIG` to `mcp_config.py` for configuring
Redis-backed session storage
- Modified `server.py` to create Redis EventStore when configured
- When enabled, uses `http_app()` with uvicorn instead of built-in `run()`
for multi-pod support
### Configuration Example
```python
MCP_EVENT_STORE_CONFIG = {
"enabled": True,
"redis_url": "rediss://elasticache.amazonaws.com:6379/1",
"max_events_per_stream": 100,
"ttl": 3600,
}
```
### Behavior
- **Disabled (default)**: Uses in-memory sessions via `mcp.run()` - suitable
for single-pod deployments
- **Enabled**: Uses Redis-backed EventStore via `mcp.http_app()` + uvicorn -
suitable for multi-pod/Kubernetes deployments
## Test plan
- [ ] Test single-pod mode (default) - verify in-memory sessions work
- [ ] Test multi-pod mode with Redis - verify sessions are shared across pods
- [ ] Verify SSL connection works with AWS ElastiCache (rediss:// scheme)
