Bug Fixes

• Coercive comparisons now collapse all numeric forms loose-equal to 0 or 1 (e.g. 1 vs '1.0', '01', '1e0'; 0 vs '0.0', -0.0, '-0') consistently with PHP's == semantics. Affects every coercive API in Summary, Set, Math, and Stream.

Improvements

• Fix NaN handling in Math::runningMax and Math::runningMin to preserve monotonicity (skip NaN values and carry forward accumulator; yield NaN when no prior value exists)
• Fix Random::percentage to always yield float (previously yielded int(0) when underlying RNG returned 0)
• Upgrade Psalm from v6 to v7 for PHP 8.5 compatibility

v2.1.0

Improvements

• Fix cycle crash with generator-returning IteratorAggregate and null handling in min/max reductions
• Fix allMatch/anyMatch/noneMatch to use boolean coercion instead of strict comparison
• Fix Sort::sort dropping elements when iterable has duplicate keys
• Fix Sort::asort dropping elements when iterable has duplicate keys
• Fix Summary::isEmpty to rewind non-Generator iterators before checking.
• Fix NaN handling in Summary::isSorted and isReversed
• Skip NaN values in Reduce::toMin/toMax/toMinMax to prevent incorrect results
• Throw InvalidArgumentException for non-serializable objects in coercive comparison mode
• Throw InvalidArgumentException for non-positive count in Transform::tee
• Throw InvalidArgumentException for step=0 in Infinite::count
• Throw InvalidArgumentException for negative position in Reduce::toNth
• Throw InvalidArgumentException for negative overlap in Single::chunkwiseOverlap
