feat: undo and redo many steps in Windows 10 Notepad (0.4.1) - #2

Notepad's edit control keeps one undo step, and a second control+Z redoes it. Code Compass now records the document at undo stops (a pause in typing, a caret move to another line, a save, and before and after each of its own commands), keeping only what changed, and control+Z, control+Y and control+shift+Z walk through those steps. Typing edits such as auto-close and indentation join the typing around them. A new document in the window (another title, or a changed text that Notepad reports as unmodified) starts a new history, so undo never brings back another file's text. Undoing back to the saved text clears the "*". On by default; a setting turns it off. Version 0.4.1. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
Review fixes for the many-step undo: - A document replaced through File > Open or File > New (Notepad calls it unchanged) starts a new history when the editor gets focus and before undo or redo, so control+Z never brings back the previous file's text. A save under a new name keeps the history only for that very text, and the save's note is dropped once the save is handled. - Histories belong to Notepad's own top-level window and title, not to the window in front (Find, Save As, another program) or to the edit control, which Word Wrap replaces. - The history starts when the editor gets focus, so the first typing in a document can be undone. - The common start and end of two texts are found block by block, so a step in a large file costs little.

Windows 10's Notepad keeps a single undo step, and its second control+Z redoes it. This adds many-step undo and redo, like VS Code:
Implementation:
undo.py(no NVDA imports) keeps only the changed part between stops; the plugin records stops on typing pauses, line moves, saves and around its own commands, and applies steps withedit_control.replace.Checked by a two-agent review with adversarial verification; its 8 findings are fixed in the second commit, with tests. 499 tests pass.
