data:image/... entries were treated as local paths and silently skipped as
"unreadable". They now ride as image_url parts only (never pasted into the
text hint, never appended to a text-mode goal). Skips and forwarding
failures log at warning since the caller explicitly asked for the images;
decide_image_input_mode gets the child's requested_provider like the CLI
and gateway callers.
Tests collapse to five invariants, including one that drives _ChildRun
and asserts the multimodal content list reaches run_conversation as the
first user turn. Docs mention data: URLs and the read guard.
