MeoNode UI v0.4.9 – Performance, Build & Test Overhaul

Release Date: 2025-11-19

Feat

build: add support for @tests alias and include tests folder in build and test configs (4dfd165)

core: optimize rendering, caching, and memory management (4f599be)
- Reworks the core rendering loop to use a more efficient, manually-managed work stack with exponential growth, reducing reallocations and improving performance for deep and wide node trees.
- Optimizes stable key generation by removing expensive shallow equality checks in favor of strict reference equality, significantly speeding up prop processing for cached components.
- Implements a high-performance MinHeap-based LRU cache eviction strategy for prop processing, replacing a slower sort-based method. This ensures that the most relevant props are kept in the cache with minimal overhead.
- Introduces CSS object hashing to accelerate prop signature generation, avoiding costly serialization of large style objects.
- Fixes several memory leaks by ensuring proper cleanup of node properties (lastSignature, lastPropsObj) and unregistering nodes from the cache cleanup registry upon eviction.
- Decouples element cache deletion from mount tracking to prevent race conditions and ensure reliable cleanup during component unmounting.

build: rename constants directory from constants to constant and update imports accordingly (9531947)

perf: overhaul performance test suite (e3bd6ac)
- Introduces a new, structured performance reporting system using cli-table3 for clear, grouped metrics.
- Refactors the entire performance test suite into logical groups: Layout Rendering, Memory Management, and Prop Processing.
- Adds comprehensive memory leak detection tests for heavy state changes and repeated mount/unmount cycles, using forced garbage collection for more accurate heap analysis.
- Extracts the large, complex CSS object into a dedicated test constant for better separation of concerns.
- Updates memoization tests to align with the new, weighted LRU cache eviction scoring.

deps: update dependencies including typescript-eslint to 8.47.0 and add cli-table3 0.6.5 (6064555)
