Editor: add tablePlugin so markdown tables round-trip and render. Task
lists (`- [ ]`), strikethrough, code (inline + fenced), headings, lists,
quotes, and links already work via listsPlugin/core/markdownShortcut. CSS:
suppress the disc bullet on task-list items (they draw their own checkbox)
and style tables.
Display: render task-list checkboxes (no stray bullet), GFM tables, and
strikethrough so the read view matches what the editor produces.
