chore: release 0.3.1 — Drive-hosted demo, keep preview thumbnail

Demo clip moved to Google Drive (committed copy was too low-res); README keeps the preview thumbnail linking to the Drive video. Restoring the thumbnail also un-breaks the demo image on the npm 0.3.0 page. Version 0.3.0 -> 0.3.1 + CHANGELOG.

 - **Demo 1 — fix a failing test suite:** both pass; the dashboard shows pxpipe cut the request to a fraction of the tokens (real, server-measured **context/token reduction**).
 - **Demo 2 — a big file-context (40 files, ~382k tokens) plus a math question and a "count this phrase" task:** the math answer (a small **text** needle) reads on both. The phrase-count needs reading the **imaged** filler — so pxpipe-on-Opus can't read it and **honestly surfaces that it won't fabricate a number** (the documented lossy limit: exact values stay text). Plain, meanwhile, bogs down counting file-by-file.
