Pasted image size lookup can now go through an async image store, gated by a flag

What

When Claude Code processes pasted or attached images while building a request, it now checks whether an image store is available and, if so, computes image dimensions in a batch through that store asynchronously instead of the previous method. This path also emits an input_image_block telemetry event counting how many images were successfully stored versus not.

Why

This is a groundwork change for handling image dimensions more efficiently when pasting or attaching images, though whether it is active depends on a gate that has not been read for this account.

How sure we are
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubtThe `tengu_pasted_image_resize_attempt` gate is unread, so it's unclear whether this path is active.
