Campaign content and listmonk credentials now live in separate
per-domain repos that install this tool at a pinned version, so a
client with access to one domain's content repo has no path to
another domain's secrets. Renames the module to the actual Gitea
host path so `go install` works without vanity-import redirects,
drops the four workflows that assumed campaigns/ content lived here,
adds real go-test CI, and rewrites the README for the tool's new
audience.

Drives listmonk's real Campaign API from git-authored Markdown+frontmatter,
so broadcast/segment emails get listmonk's mature unsubscribe/bulk-send/
attachment handling instead of reimplementing it. sync only ever creates or
updates a draft (idempotent, diff-based, refuses to touch a non-draft
campaign); a pushed send/<slug> tag or manual workflow run is the only way
to actually trigger a send. Includes list-name resolution, segment_query
materialization into managed lists, content-hash-deduped attachment
uploads, and an automatic post-sync preview email.
