AppKit lacked a public text attachment class, preventing rich text documents
from embedding or inserting images.
* AppKit/CPTextView/CPTextAttachment.j:
- Implement CPTextAttachment (modelled on NSTextAttachment) supporting
initialization via data and file type, contents, file types, images,
bounds, and keyed archiving.
- Adopt a TextKit 2-style view rendering architecture that scales images
to fit text container width and triggers layout updates upon asynchronous loading.
* AppKit/CPTextView/CPTextStorage.j:
- Update attributedStringWithAttachment: to accept CPTextAttachment instances
alongside direct views, routing rendering through existing attachment pathways.
* AppKit/CPTextView/CPTextView.j:
- Implement the insertImage: action (invoking browser file pickers) and
Command-V paste handling for images.
- Configure inserted attachments with responsive view instances scaled to
text width, omitting live views during pasteboard archiving.
* AppKit/CPTextView/CPTextContainer.j:
- Adjust attachment bounds to match updated container widths during layout invalidation.
* AppKit/AppKit.j:
- Export CPTextAttachment.
* Tests/AppKit/CPTextAttachmentTest.j:
- Add test coverage for data URLs, archiving, width scaling, insertion,
and serialized text output.
* Tests/Manual/TextEditor/Resources/MainMenu.xib, MainMenu.cib:
- Add Edit > Insert Image… menu item.
* Tests/Manual/TextEditor/WORKLIST.md:
- Mark image insertion testing as completed; log remaining image tasks as open.
Rich text documents now support embedded images inserted via file selection or clipboard paste.
Previously CPText was in CPTextView.j, now it is in CPText.j.
It fixes some other circular import as well, fixes some global var to import.
Fixed some code style.
