chore: rename app to 自动化工具 and exe/release to CMBot

Functional/build-level rename only:
- version.py APP_NAME -> 自动化工具 (window title)
- build.ps1 exe/release name AutoPrint -> CMBot
- docs packaging/structure examples AutoPrint -> CMBot

Descriptive product name in narrative docs is left unchanged.
