Pull request overview

Refactors test word storage from string[] (+ parallel section index list) to structured word objects (text, display, textWithCommit, sectionIndex) as a prep step for future work.

Changes:

• Introduce Word object model in test-words + migrate call sites from getText/getCurrentText to get/getCurrent
• Update UI/rendering + caret/keymap targeting to use display/text/textWithCommit as appropriate
• Adjust event log + unit test mocking to reflect the new structure
