feat: add Tap, Transpose, Unzip, ParallelReduce, and Replicate (#49)
* 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

* 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%
