Align Ctrl+Right behavior with Ctrl+Left
The word navigation logic for Ctrl+Right incorrectly included trailing
delimiters (spaces, punctuation) after the word. This created an
asymmetric and unintuitive experience compared to Ctrl+Left.
This commit adjusts the logic in both TInputLine and TEditor.NextWord
to first skip delimiters and then skip the word itself, ensuring the
cursor stops precisely at the word boundary.
