Fix broken leaky ReLU operator (#36)

[albiol2004]

Added

• aie_kernels/aie2/leaky_relu.cc : AIE2 kernel for Leaky ReLU (vector width 16, matching the AIE2P version's structure with aie:: API).

Changed

• iron/operators/leaky_relu/design.py : Fixed kernel parameter type: np.dtype[xfr_dtype] → xfr_dtype. The previous form produced a GenericAlias that MLIR couldn't convert to a function type, causing TypeError during compilation.
• iron/operators/leaky_relu/test.py : Removed @pytest.mark.skip decorator.
• README.md : Updated Leaky RELU row: removed "(WIP)", added NPU1 support checkmark, changed status to green.

Removed

Nothing.

Test results

• 31/31 Leaky ReLU tests pass (input lengths 1K–8K, 1–8 columns, 1–2 channels, alpha=0.01)
• No regressions in ReLU (8/8) or SiLU (4/4)
