v0.1.7

This release focuses on hardening the core engine for large-scale applications with improved failure tracking, cyclic dependency detection, and enterprise-grade metadata.

Core Improvements (@pulse-js/core 0.1.7)

• Cyclic Dependency Detection: Added a robust stack-based detection mechanism that catches infinite reactive loops (A -> B -> A) and reports them as descriptive failure reasons instead of causing stack overflows.
• Persistent Dependency Insights: The .explain() graph now persists even after a failure. Previously, failing early would clear downstream dependencies; now it remembers the last known graph for better debugging.
• Structured Reason Metadata: Introduced the GuardReason interface. Evaluators can now throw objects with code, message, and meta to provide rich error context to the UI.
• Semantic State Preservation: When a failed Guard re-evaluates, its lastReason is preserved while pending, preventing UI flickering and allowing users to see the previous error while the next attempt is in progress.
• Flexible Pending State: Returning undefined from a Guard evaluator now explicitly marks it as pending, simplifying data fetching and “not ready” patterns.

DevTools Improvements (@pulse-js/tools 0.1.4)

• Metadata Rendering: The inspector now renders structured failure reasons, including error codes and JSON metadata snippets.
• Evaluation State Tracking: Visual indicators for lastReason when a guard is in a pending state after a failure.
• Dependency Status: Dependency lists now show the status of each dependent guard for faster troubleshooting.

React Integration (@pulse-js/react 0.1.4)

• Updated Dependencies: Bumped to use @pulse-js/core@0.1.7 and @pulse-js/tools@0.1.4.
