chore(release): rename @gsxdsm/fusion to @runfusion/fusion 0.0.1

Move the publishable CLI under the new @runfusion npm org for the first
public release. Reset version to 0.0.1 since the previous name was never
actually published. Rewrite packages/cli/README.md (the npm page) to
mirror the root README marketing — Fusion logo, reel GIFs pulled from
raw.githubusercontent.com, feature grid, tagline — and fix the stale
dustinbyrne/kb image link and ISC-vs-MIT license mismatch. Propagates
the name through root scripts, RELEASING.md, workflows, and docs.
