fix: correct 'becuase' typo in code comments

[wwwmake-ui]

Fix the misspelling of \�ecuase\ in three code comments:

• \src/component/helper/cursorHelper.ts\
• \src/coord/matrix/Matrix.ts\
• \src/chart/treemap/treemapLayout.ts\

Verification

• Checked the diff of each changed file via the GitHub compare API; only the typo on the comment lines was changed.
