The claude project watcher failed to start when the project directory name contained an underscore

[patrick-fu]

I found that I never receive messages from the terminal on my mobile device in some project.

Then I checked happy's log and found that the file path monitored by the watcher was incorrect.

My project folder is ~/dev/ai_follow, but the claude project jsonl file is under /Users/patrickfu/.claude/projects/-Users-patrickfu-dev-ai-follow ( Notice that Claude Code replaced the underscore with dash)

Then I found that the path happy was trying to search for was incorrect, it using underscores.
