// REAL survey: send an image to EVERY chat LLM (all providers with active creds) and
// record how each model behaves vs its declared vision capability.
// Purpose: discover where non-vision models 400 on image input (need auto-strip) and
// where capability data is wrong. This is a SURVEY: it logs a table, it does not fail
// on capability mismatches (only real harness errors throw).
