Tree decorations could carry only a two-character badge and a tooltip. decorations.set-file-note (API 1.7) shows one line of muted text (at most 200 characters, optional tooltip) after a file or folder name in the project tree, replacing that tree set's item for the file and sharing the tree-set limits. The SDK wraps it as host::set_file_note with a mock; checked-in components rebuilt.
