[BUG] claude --resume shows "No conversations found" despite session directories existing

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

Description:
Session directories exist in ~/.claude/projects/ with subagent .jsonl files, but the main conversation .jsonl files are missing. This causes --resume to fail even though sessions were
recently used.

Environment:

• macOS Darwin 25.2.0
• Claude Code CLI

Evidence:

• cleanupPeriodDays is set to 0
• Session directories exist (e.g., a96feba5-76c5-4844-b54a-5b934eec1110/)
• Each contains subagents/ folder with .jsonl files
• No main *.jsonl file exists at the session root level
• Sessions as recent as yesterday (Jan 14) are affected

What Should Happen?

Expected: Main conversation files should be saved and --resume should find them.
