* fix(editor): preserve sibling tasks beneath ordered list items
* fix(editor): preserve wrapped inline markup in task items
* fix(editor): keep nested task continuations valid and editable
* fix(editor): keep literal task markers out of mixed checklists
* fix(editor): apply review fixes to task-list parsing stack
- Trim synthetic test matrices to the behavioral cases
- Regenerate pnpm-lock (drops a stale github-slugger importer entry)
- Assert the plain bullet's node type under an ordered parent
* fix(editor): keep one-column-deeper ordered tasks as sibling checkboxes
Dedent an ordered item's task block by the first task's column instead of
keeping its leading whitespace. A task one column deeper stays a sibling
checkbox, and text at or within the first task's column stays nested as
before. Strip leftover paragraph indent from task children.
