fix: update validation script to allow legitimate public info

Security Validation Improvements:
- Added pm.me to allowed email domains (public contact email)
- Added code block detection to skip infrastructure patterns in examples
- Port numbers in markdown code blocks no longer flagged
- Fixes false positives blocking README.md sync

Workflow Improvements:
- Added issues:write permission to notify-failure job
- Fixes 403 error when creating failure notification issues

This allows the public README with code examples and contact info
to pass validation while still blocking actual security issues.
