Add or replace a file in a template’s bundle

Registers a new file in your organization’s template library and puts it in this template’s bundle under name. A file already in the bundle under that name is swapped out.

Two request shapes:

• { name, content } — the text of a source file, stored for you (up to 2 MB).
• { name, mimeType } — for binary assets: the file is registered and the response carries uploadUrl; PUT the bytes there with a Content-Type exactly equal to the mimeType you sent.

The replaced file is detached, never deleted — anything that already rendered with it keeps working.
