BloggerDeliverer posts each briefing (markdown -> HTML, H1 becomes the
post title with the report headline) via the Blogger API v3 using a
long-lived refresh token; `us2kr blogger-auth` runs the loopback OAuth
flow once and prints the BLOGGER_* lines for .env. Enabled only when
all four BLOGGER_* settings are present.

Optional meta-search source (SEARXNG_BASE_URL): per-query isolation,
time_range=day, merged and deduplicated with the RSS feeds. Briefings
still publish on RSS alone if the instance is down.
