Do not expose an uninitialized editor to extension factories.
createLexicalWrapper invokes the factory before assigning wrapper.editor. The factory type exposes LexicalWrapper.editor as non-nullable. A factory that uses wrapper.editor can therefore throw before the editor mounts.
Pass a factory context that excludes editor, while preserving mapping, or invoke the factory after editor initialization.

Custom checklist behavior not registered
High Severity
Extension-based editors now mount CheckListExtension in place of the old list() path, which also registered the custom checklistPlugin. That plugin owns checkbox hit-testing for the ::before control, strips checkbox tabindex, and handles Cmd/Ctrl+Enter toggles, so those behaviors are gone on the main markdown editor and builder surfaces.

Note
High Risk
Touches core markdown editor initialization, collaboration sync wiring, and plugin registration across many surfaces; behavior should be equivalent but lifecycle/order changes can affect editing, undo, and sync edge cases.
Overview
This PR begins migrating Lexical editor setup from the fluent PluginManager API to Lexical’s extension graph (
@lexical/extension), with apluginExtensionhelper that wraps existing register/cleanup callbacks as named extensions.createLexicalWrappernow builds editors viabuildEditorFromExtensionsand accepts anextensionscallback;createLegacyLexicalWrapperkeepsPluginManagerfor surfaces not yet migrated (title editors, instructions, collab surface, code markdown, etc.). The markdown builder (buildHandleFromConfig) composes the same features as extensions instead ofplugins.richText().list()…, dropspluginsfromEditorHandle, and queues custom.use()plugins as extension entries.The main
MarkdownEditorregisters its large plugin set througheditorExtensions()(rich text, shortcuts, collab history, menus, tables, AI/diff flags, etc.); container-dependent drag-insert / draggable-block plugins stay on Solid lifecycle at root connect.CollabProviderno longer takespluginManager—Loro lexical sync is started/stopped with explicit cleanup.Call sites that hung behavior off
plugins.use/useReactivenowautoRegister(plugin()(editor))or SolidcreateEffectcleanup (comments, popups, floating menus, canvas text wrap). Tests cover extension lifecycle and custom plugin disposal.Reviewed by Cursor Bugbot for commit b0cc741. Bugbot is set up for automated code reviews on this repo. Configure here.
