refactor: trim trailing whitespace from commit message

[rm-hull]

Ensures cleaner commit messages by stripping trailing spaces, tabs, and carriage returns from each line before processing. Added a helper function with corresponding unit tests to verify behavior.

This was causing some glitches with bubbletea text component too.

Code Review

This pull request introduces a helper function trimTrailingSpaces to remove trailing spaces, tabs, and carriage returns from each line of a string, and applies it to the commitMessage in the Update method of the UI model. Additionally, comprehensive unit tests have been added to verify the behavior of this helper function. There are no review comments, and I have no feedback to provide.
