test : add unit tests for repo-analytics-types.ts

[tmdeveloper007]

Summary of What Needs to be Done: Add unit tests for the repo analytics type guards and validation helpers in src/lib/repo-analytics-types.ts, covering any exported utility functions (if any).

Changes that Need to be Done: Create test/repo-analytics-types.test.ts. Note: this file primarily exports TypeScript interfaces. If no runtime functions exist, add a smoke test that verifies the type exports are correctly structured (e.g., testing that a valid ExplorerRepoCardData object passes type checks).

Impact that it would Provide: Provides baseline test infrastructure for the repo analytics module and ensures type exports are available for consumer code.
