feat(markdown): support HTML superscript links (#8307)

* feat(markdown): support HTML superscript links

* Add HTML superscript citation links to the rich markdown editor

- Introduce marked-based tokenizer support for `<sup><a>` citation
  links, with a shared editor context so key/link handlers can resolve
  selection status and open an action bubble for citation atoms
  (which markdown setLink/unsetLink can't edit).
- Extract clipboard-write logic shared by cut and cut-visual-line into
  rich-markdown-clipboard-write.ts, and surface a cut-limit error when
  clipboard readback fails.
- Fix MarkdownPreview same-file anchor scrolling to run before the
  unknown-ownership guard so ambiguous folder-workspace ownership
  still scrolls within the open document.
- Keep search's replace-disabled state derived from live matches
  instead of a stale snapshot.

* Update lockfile to dedupe stale package versions after dependency resolu

- Removes duplicate/superseded resolutions (older @babel/* versions, fs-extra 11.3.4/11.3.5, plist 3.1.0, semver 7.7.4) left over from a prior install
- Aligns transitive deps to the single resolved versions already in use elsewhere in the tree
