feat(config): load ignore_repos from startup-config.json

- Load daemon config by matching current directory
- Override ignore_repos from config file (takes precedence over env var)
- Fall back to empty list if config not found

Usage: Edit ~/.config/commits/startup-config.json
No environment variables needed!
