feat: enhance session ID calculation and plugin management

- Updated `calculate_session_id` method in `SessionUtils` to include optional `account_id` and `scope` parameters for more granular session ID generation.
- Added new environment variables in `plugin_runtime` for external plugin dependencies and global configuration snapshots.
- Introduced methods in `RuntimeComponentManagerProtocol` for loading and reloading plugins globally, accommodating external dependencies.
- Enhanced `PluginRunnerSupervisor` to manage external available plugin IDs during plugin reloads.
- Implemented dependency extraction and management in `PluginRuntimeManager` to handle cross-supervisor dependencies.
- Added tests for session ID calculation and message registration in `ChatManager` to ensure correct behavior with new parameters.
