[Bug]: clear command does not reset context for codex

Before submitting

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area

apps/web

Steps to reproduce

1. Open a thread with Codex as a provider
2. Write some prompts
3. Try to reset via /clear command in chat
4. Codex says that context is cleared
5. Ask Codex about what's in context

When command is invoked, context is not cleared even though Codex says so. When you ask about what's in context, it will tell you the remaining context before the reset.

Expected behavior

• /clear command should be suggested when typing into the chat
• context should actually be reset when command is invoked

Actual behavior

• /clear command does not show up in suggestions
• context is not cleared when command is invoked

Impact

Major degradation or frequent failure

Workaround

Open a new thread instead of clearing current conversation

Start in apps/web and trace the /clear command from chat suggestions through its Codex handling. Reproduce the issue with a Codex thread, then verify that /clear appears while typing and that asking about prior prompts no longer reveals the old context. Confirm the existing new-thread workaround is no longer needed.
