• Removes the redundant duplicate {index} directive block (and its trailing blank line) in lectures/numpy.md, leaving a single directive.
• Updates the translation state file with the new source SHA, sync date, and tool version.

File	Description
lectures/​numpy.md	Removes the duplicated {index} directive under the Matrix Multiplication heading, leaving one correct directive.
.translate/​state/​numpy.md.yml	Updates source-sha, synced-at, and tool-version to reflect the new sync state.
