fix: handle non-array GitHub API responses

[Roshnicoderr]

Description

Fixes the GitHub API response handling issue described in #225 .

Changes

• Handle 204 No Content responses in fetchWithCache() by returning an empty array.
• Validate responses from fetchContributors(), fetchIssues(), and fetchPulls() before spreading them into the result array.
• Gracefully stop pagination when GitHub returns a non-array response.

Problem

Some GitHub API endpoints can return responses that are not arrays.

For example, repositories with disabled Issues can return an object containing a message field, while some valid requests can return 204 No Content.

Previously, these responses could cause:

TypeError: data is not iterable

or:

SyntaxError: Unexpected end of JSON input

This change prevents those responses from crashing the data-fetching pipeline.

Testing

• npm run build passes successfully.
• git diff --check passes successfully.

Summary by CodeRabbit

• Bug Fixes
  • Improved handling of empty GitHub API responses.
  • Prevented contributor, issue, and pull request listings from failing when paginated responses contain no usable data.

Walkthrough

GitHub API handling now returns an empty array for HTTP 204 responses. Pagination stops when contributor, issue, or pull request responses are not arrays.

Changes

GitHub response handling

Layer / File(s)	Summary
Response and pagination guards src/services/github.js	fetchWithCache returns [] for HTTP 204 responses. The contributor, issue, and pull request pagination loops stop when the response is not an array.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to c94d4

Empty GitHub responses no longer fail parsing, but repeated 204 responses will not be cached and can cause unnecessary API requests until the empty result is stored.

I have updated the 204 No Content handling to cache the empty result before returning it.
