* feat: add Tap, Transpose, Unzip, ParallelReduce, and Replicate - Add Tap: for side effects/debugging in pipelines - Add Transpose: flip matrix rows and columns - Add Unzip: split tuple slice into two slices - Add ParallelReduce: parallel reduction (experimental) - Add Replicate: create n copies of a value Comprehensive tests included for all functions. Resolves Issues 21, 22, 23, 24, 25 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> * test: improve ParallelReduce test coverage to 97.5% Add comprehensive tests covering: - Default workers (workers <= 0) - Negative workers - Error handling and propagation - Context cancellation during execution - Context timeout - Single element processing - Many workers (more workers than elements) - Benchmark for performance validation Coverage increased from 68.75% to 97.5% 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com> --------- Co-authored-by: Claude <noreply@anthropic.com>

// Tap applies a function to each element for side effects (like debugging/logging)
|
|
// and returns the original slice unchanged. Useful for debugging pipelines.
|
|
//
|
|
// Example: Tap([]int{1,2,3}, func(n int) { fmt.Println(n) }) → [1,2,3] (and prints each)
