Increase test coverage across lowest-coverage packagesclaude/improve-test-coverage-iBkwc
Major coverage improvements: - safehttp: 46.7% -> 93.3% (SafeDialer, redirect checking, SSRF protection) - api: 81.8% -> 96.4% (HandleImport 0% -> 100%, stream errors, content types) - importer: 85.3% -> 94.7% (ImportFeeds dispatcher, OPML nesting, edge cases) - cmd/neko: 77.1% -> 85.4% (purge, secure-cookies, minutes, allow-local flags) New tests added: - Security regression tests (CSRF token uniqueness, mismatch rejection, auth cookie HttpOnly, security headers, API auth requirements) - Stress tests for concurrent mixed operations and rapid state toggling - SSRF protection tests for SafeDialer hostname resolution and redirect paths https://claude.ai/code/session_01XUBh32rHpbYue1JYXSH64Q
