@cursoragent CI is failing fix it

[cursor]

Fixed the CI failure. TypeScript strict mode flagged lines[i] as possibly undefined. Added a guard at the start of the loop to ensure line is defined before use.

Fix applied:

• Added if (line === undefined) continue; check after accessing lines[i]
• This ensures TypeScript knows line is defined for all subsequent uses in the loop

Verification:

• All tests still pass (13/13)
• TypeScript type checking passes for the jsrepo package
• No linter errors

The CI should now pass. The guard clause satisfies TypeScript's strict null checking while preserving the existing behavior, since lines[i] should never be undefined when iterating within bounds.
