Authors write a ```columns fenced block (columns separated by a line of
===); Pandoc passes the body through verbatim as <pre class="columns">,
and a new post-Pandoc transform in lib.wiki.expand_columns expands it
into a flex <div> of <poem> columns. Runs entirely Pi-side before the
MediaWiki API write — no wiki template or PHP extension required.
The transform lives in shared lib/wiki.py (called from markdown_to_wikitext),
so it is universal across all pipelines. Stdlib only; no new deps.
Docs: SCHEMA.md author contract + songs/root decision logs.
Also ignore __pycache__/.

New pipeline at pipelines/ses/ publishes mikkeli/ses-light-novel to
the SES: MediaWiki namespace. All pages get Category:SES and
Category:SES:<type> (type from frontmatter, fallback to parent dir name).
Shared functions (connect_wiki, markdown_to_wikitext, strip_first_h1,
AUTO_BANNER_PREFIX) extracted from songs/publish.py into lib/wiki.py;
songs refactored to import from there.
Also adds publish-ses.yml workflow stub and updates Dockerfile and
root README.
