Summary:
Executing the /clear command in Gemini CLI resets the conversation and generates a new session ID. While the Config object is updated with this new ID, the internal Storage instance remains tied to the initial session ID because it is set at construction and cannot be modified. As a result, the agent's system prompt and planning/tracking tools continue to use the file paths from the previous session, leading to "Plan Mode" pointing to the wrong directory.

Steps to Reproduce:

1. Start a session and enter Plan Mode.
2. Create a plan and approve.
3. Run /clear.
4. Enter plan mode.
5. Observed Behavior: It is showing approved plan from step 2.
6. Expected Behavior: It is a new session, there should be no approved plan.
