Subject: [PATCH] fix(editor): preserve nested ordered lists through readonly
 render (#1512)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Default @tiptap/markdown serializer emitted nested list items with 2-space indent, but CommonMark (remark-gfm) requires ≥3 spaces under a `1.` marker — so ReadonlyContent (autopilot detail / issue / comment) flattened nested ordered lists, with third-level items glued onto their parent line. Configure Markdown extension with indentation.size = 3.

Closes #1510
