feat\!: rename baoyu-imagine→baoyu-image-gen, baoyu-image-cards→baoyu-xhs-images (v2.0.0)

BREAKING CHANGE: removed `baoyu-imagine` and `baoyu-image-cards`. All
functionality now lives under `baoyu-image-gen` and `baoyu-xhs-images`
respectively. Cross-skill `## Image Generation Tools` examples updated
across baoyu-article-illustrator, baoyu-comic, baoyu-cover-image,
baoyu-infographic, and baoyu-slide-deck.

Migration: existing `~/.baoyu-skills/baoyu-imagine/EXTEND.md` configs are
auto-renamed to `…/baoyu-image-gen/EXTEND.md` on first run via the
legacy-path resolver in `scripts/main.ts`.
