Session titles show API 404 error for deprecated model claude-3-5-haiku-20241022

Bug Description

When listing past sessions, almost all session titles display an API error instead of the actual session title:

API Error: 404 {"type":"error","error":{"type":"not_found_error","message":"model:claude-3-5-haiku-20241022"},"request_id":"req_011CZFVwHXnjMdMAxKE…"}

Steps to Reproduce

1. Have existing sessions in Claude Code
2. List past sessions
3. Observe that session titles show the 404 API error instead of generated titles

Expected Behavior

Session titles should display a human-readable summary of each session's conversation.

Actual Behavior

Nearly all session titles show the API 404 error referencing claude-3-5-haiku-20241022, which appears to have been deprecated/removed from the Anthropic API.

Suggested Fix

Update the model reference used for session title generation from claude-3-5-haiku-20241022 to a currently available model (e.g., claude-haiku-4-5-20251001).
