Implements time-based caching for non-specific versions (currently @latest) to avoid repeated npm lookups within a configurable time window (default 5 minutes). Features: - Caches resolved versions for @latest package requests - 5-minute cache timeout (configurable) - Cache stored in OS temp directory - Graceful fallback on cache errors - Only caches non-specific versions (exact versions like @4.17.21 are not cached) This solves issue #17 where packages like lodash@latest would be npm installed again within minutes instead of using cached results. Testing: - Added comprehensive test suite for caching functionality - Added demonstration script showing cache performance improvements - All existing tests continue to pass Future enhancements can extend this to major version ranges like @4, @4.x, etc. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
