host: blog published-post read endpoint GET /<slug>/ -> HTML, 156/156

lib/host/blog.sx serves blog posts as HTML at GET /<slug>/ (the original
strangler target, Quart blog post_detail). A post is a content-on-sx CtDoc
rendered via content/html; anonymous + world-visible. In-memory slug->doc
registry now (host/blog-lookup swappable for a persist-backed content stream
later, handler/route unchanged). :slug catch-all mounted LAST so /feed,
/health, /internal/* take precedence. Needs the Smalltalk+persist+content
preload chain + (st-bootstrap-classes!)+(content/bootstrap!) — blog.sx
self-bootstraps at load. serve.sh loads the chain + seeds a welcome post.
Ledger gains the migrated blog post-detail (off-Quart 50% -> 53%).

LIVE: blog.rose-ash.com/welcome/ renders real HTML through Cloudflare->Caddy;
/feed still JSON (precedence verified), unknown slug 404.
