LLeMbas CLI 1.5.1

An image counted as half a million tokens: the context estimate measured its
base64 as text, so a 1-3 MB screenshot read as "context at 150-280%" the
moment view_image added it, and the session compacted after every image.
An image now counts by its dimensions (28 px patches, at most 16k tokens, a
flat 1600 when unreadable) everywhere the CLI estimates -- the meter, pruning,
/context and the no-usage fallback of all five dialects. Images over 1600 px
or 500 KB are shrunk to 1600 px when ImageMagick is there.

+- **An image counted as half a million tokens.** The context estimate measured an image's base64
+  as text, so a 1–3 MB screenshot read as "context at 150–280%" the moment `view_image` (or an
+  `@` attachment) added it, and the session was compacted -- after every image, since the summary
+  drops pictures and the model looked again. The provider's own count, a few thousand tokens, was
+  never in question. An image now counts by its dimensions (28-pixel patches, at most 16k tokens;
+  a flat 1600 when the size cannot be read), everywhere the CLI estimates: the context meter,
+  pruning, `/context`, and the estimate a provider that reports no usage falls back to.
+- **Screenshots are sent at 1600 px.** Any image over 1600 px or 500 KB is shrunk to 1600 px on
+  its longer edge when ImageMagick is there (only files over 3.5 MB were before): no more detail
+  than the model is billed for, and a lighter request.
