Add tests for client/tailscale and ipn/store/mem
- client/tailscale: Add 25+ test functions covering LocalClient operations - DoLocalRequest, Send, Get200, error handling - AccessDeniedError and PreconditionsFailedError - Context cancellation, auth headers, concurrent access - Increases coverage from 0.02 to ~0.30 ratio - ipn/store/mem: Add comprehensive tests (30+ test functions) - Read/Write state operations - JSON export/import with round-trip verification - Concurrent access safety - Edge cases (empty keys, nil data, overwrites) - Performance benchmarkspull/17963/head
