v0.6.0 Release

Highlights

• Persistent query result caching: Query results can now be persisted to disk via the --cache-dir CLI flag or SELECTOR4NIX_CACHE_DIR environment variable, allowing cache survival across process restarts
• Module support for persistent caching: Added enablePersistentCaching option to NixOS, nix-darwin, and Home Manager modules
• Internal refactoring: Ongoing refactoring of the internal architecture to improve long-term maintainability
• System testing: Added system tests for cache persistence, and parallelized the CI test workflow for faster feedback

New Features

• Added optional persistent caching for NAR info and NAR file location query results, configurable via --cache-dir flag, SELECTOR4NIX_CACHE_DIR environment variable, or the enablePersistentCaching module option
• Set a more conservative default for maximum concurrent requests
