[BUG] --resume picker does not show session when project path contains underscores

What's Wrong?

When the working directory path contains underscores (e.g., D:\Desktop\workspace\xx_xx_xx), Claude Code encodes the path into the ~/.claude/projects/ folder name by converting underscores to hyphens (result: D--Desktop-xx-xx-xx.

The session file exists on disk and is valid, but claude --resume interactive picker does not list it.

Workaround: claude -r <session-id> works correctly.

Now I'm using claude --resume with the sessionId command to continue my work, but I need to go into the folder to get the session ID, which is very inconvenient.
