Subject: [PATCH] fix: enforce exact separator form in md-table-padding check

Previously the check trimmed each separator cell before comparing
against the allow-list, which meant `| --- | --- |` passed as
`---`. The documented rule requires the tight `|---|---|` form;
compare the raw cell so space-padded separators fail too.
