[BUG]: Missing pagination safety guard in fetchContributors() and fetchIssues()

[KaranUnique]

Bug Description

Both fetchContributors() and fetchIssues() iterate through paginated GitHub API responses using an unbounded loop:

js :
for (let page = 1; ; page++) { ... }

Steps to Reproduce :

1. Open services/github.js.
2. Navigate to fetchContributors() and fetchIssues().
3. Observe that both functions use an unbounded pagination loop without a maximum page limit or response validation.

Environment Details :

• OS: Windows 11
• Browser: Brave
• Node.js: 22.18.0

Impact :
