A summary of the changes CodeRabbit can apply:

• Implement change-detection to enable save only when edits exist by updating NoteEditViewModel (add initialRecordInfo, isSaveButtonEnabled, formDataChanged action, hasFormChanges method), NoteEditViewController (bind isSaveButtonEnabled, subscribe and forward formDataPublisher), and NoteEditView (add formDataPublisher, initialize button disabled, setupFormChangeObservers, and setSaveButtonEnabled).

• Add reactive form-change tracking and save-button enablement: introduce a formDataPublisher and text-change observers in NoteEditView (NoteEditView.swift), add setSaveButtonEnabled UI method, subscribe to formDataPublisher in NoteEditViewController (NoteEditViewController.swift), extend NoteEditViewModel to store initialRecordInfo, track isSaveButtonEnabled, handle formDataChanged and emotionSelected actions, and add a hasFormChanges helper to compute changes (changes saved across .sed-tmp files and updated View/ViewModel source files).
