- Add comprehensive unit tests for cursor-auth.test.ts
- validateToken: valid/invalid tokens, short tokens, UUID formats, empty strings
- extractUserInfo: JWT parsing, email handling, non-JWT tokens, malformed base64
- saveCredentials/loadCredentials: round-trip, invalid JSON/types, missing fields
- checkAuthStatus: authenticated/not authenticated, expired tokens, JWT exp, invalid dates
- deleteCredentials: delete existing/non-existent files, multiple deletes
- All tests use CCS_HOME env var for isolation, real file I/O, no mocks
- Fix dead try-catch around new Date() in checkAuthStatus()
- Replace try-catch with isNaN check (new Date('garbage') returns Invalid Date, not throw)
- Properly handle Invalid Date by checking isNaN(getTime())
- Fix email populated with sub claim in extractUserInfo()
- Change email: decoded.email || decoded.sub to email: decoded.email || undefined
- Prevent non-email values (UUIDs) from populating email field
- Add type guards for JSON.parse result in extractUserInfo()
- Cast to Record<string, unknown> and validate types
- Use typeof checks for email, userId, exp fields
