A token that may write opens a writable folder. A save sends the file
whole through write_file with the revision it was read at, or "none" for
create-only, so aindrive refuses it as a conflict when the file moved on;
saves are capped at one 1 MiB transfer, which a table-driven encoder fits
into one call's fuel. A save whose answer is lost, or that the drive's
device timed out on, is reported with an unknown outcome. Deleting takes
one file; folders are refused because delete_path is recursive and
listings hide entries such as .git.
