ConnectionState

Category: Mcp_client

Source: connection_state.dart

Connection state machine for an [McpClient] against a single MCP server, plus the backoff-with-jitter helper.

Pure data + a pure function. The state-transition logic itself lives in client.dart and pool.dart.

[McpDisconnectReason] re-exports from glue_core so the wire enum stays single-sourced — the same value flows through events and the state machine.
