- Added auto-reconnect capability for MCP servers with SSE stream monitoring and exponential retry backoff.
- Added tool-level reconnect handling for retriable connection errors (ECONNREFUSED, ECONNRESET, 404/502/503).
- Added `/mcp reconnect <name>` command for manual MCP server recovery.
- Improved reconnect robustness by aborting retries when MCP configuration changes via epoch checking.
- Extended transport reconnect handling to all transport types (stdio, HTTP/SSE) with unified onClose logic.
- Added comprehensive test coverage for MCPManager reconnect behavior and tool-level abort propagation.
