feat: implement OpenClaw process owner and runtime path utilities

- Add OpenClawProcessOwner class to manage the lifecycle of the OpenClaw process.
- Introduce utility functions for managing OpenClaw runtime paths.
- Update session store to normalize agent session keys and migrate existing keys.
- Refactor main process to handle local provider API routing through a new dispatch function.
- Enhance token usage writer to utilize a new session key parsing function.
- Create agents management store to handle agent data and interactions.
- Update chat store to integrate agent selection and session management.
- Introduce AgentsSection component for displaying agent information in the UI.
- Refactor HomePage to support agent selection and display current agent.
- Update routing to reflect new agents page structure.
