Replace loose .includes('github.com') check with exact hostname
comparison to prevent lookalike domains like github.com.evil.com.
Add isStrictGitHubUrl validator and apply it as a Zod refinement
on the CSV row schema.

There was a problem hiding this comment.
[WARNING]: isStrictGitHubUrl() allows non-HTTPS GitHub URLs
If this URL is ever used as a clickable link (emails, UI, logs), allowing http: increases exposure to downgrade/MITM. Consider requiring https: in addition to the strict hostname check.
Suggested change
| return parsed.hostname === 'github.com' || parsed.hostname === 'www.github.com'; | |
| return parsed.protocol === 'https:' && (parsed.hostname === 'github.com' || parsed.hostname === 'www.github.com'); |
