* markdown: fix: route undo and redo to the document history
The Agents window Markdown editor attaches an EditContext, so the browser
keeps no native undo history and the Cmd+Z / Cmd+Shift+Z chords never
reached VS Code. Wire them to the backing TextDocument's own history:
- editor.ts: pass a `historyStrategy` to `EditorController` that posts
`{ type: 'history', command }` to the extension. `record` is omitted so
the TextDocument stays the single source of truth (no second local stack
that would drift from the Edit menu, dirty state and hot exit).
- markdownEditorProvider.ts: run the built-in `undo`/`redo` command; the
active custom editor input scopes it to the resource's IUndoRedoService.
- editor.ts: apply host `update` via `replaceSourceText` instead of
`sourceText.set`, so the caret is mapped through the change (e.g. after an
undo shrinks the document) and stale pending-paragraph state is cleared.
Depends on the @vscode/markdown-editor API from microsoft/vscode-packages#189;
the pinned version must be bumped once that is published.

* markdown: chore: bump @vscode/markdown-editor to 0.0.2-40
Pick up the published `@vscode/markdown-editor` release that ships the
`IHistoryStrategy` / `EditorControllerOptions.historyStrategy` and
`EditorModel.replaceSourceText` APIs (microsoft/vscode-packages#189) the
undo/redo integration depends on. Dependency set is unchanged from
0.0.2-26; lockfile integrity matches the published tarball.
