Fix PII: replace /Users/username/ with ~ and <username> placeholder

Replace hardcoded user paths that triggered gitleaks PII detection:
- /Users/username/ → ~/
- /Users/user/ → ~/
- -Users-username- → -Users-<username>- (normalized paths)

Also fix the sed example to use <home> placeholder instead of
regex pattern that would match actual usernames.
