Two independent OpenCode tabs unexpectedly share state/session

Description

I had two separate OpenCode tabs open, intended to operate independently. However, actions and state from one tab appeared to synchronize with the other tab. The two tabs behave as though they were connected to the same underlying session/state.

This is unexpected because each tab should maintain its own independent UI/session context.

Expected behavior: Two OpenCode tabs should operate independently, with actions, prompts, and session state isolated per tab/session.

Actual behavior: The tabs appear to share or synchronize state, causing activity in one tab to affect the other.

Steps to reproduce

1. Close every OpenCode instance.
2. Confirm no OpenCode processes remain.
3. Open Terminal 1.
4. Start OpenCode.
5. Create/open Session A.
6. Send a distinctive message:
   "THIS IS SESSION A TEST 12345"
7. Open Terminal 2.
8. Start a completely separate OpenCode instance.
9. Create/open Session B.
10. Send:
    "THIS IS SESSION B TEST 67890"
11. Observe whether Session A and Session B remain independent.
