Build the dim label line shown above an inline image, e.g. ` screenshot.png 1920×1080`, with a trailing show/hide badge (`[Alt] [⇧] [I] hide` / `[Al

Cheap presence probe: is this inline image already registered in the in-memory render cache? One mutex lock + bounded key scan; no payload hashing, no

The chat scroll offset the renderer actually used on the most recent frame (after clamping and after resolving any pending history anchor).

Total wrapped line count of the chat transcript on the most recent frame. Returns 0 if no frame has been rendered yet.
