This is the first in a series of PRs to introduce a ProseMirror-based WYSIWYM editor experience alongside our current textarea Markdown editor. Behind a hidden site setting, this PR adds a toggle to the composer toolbar, allowing users to switch between the two options. Our implementation builds upon the excellent ProseMirror and its non-core Markdown module, using the module's schema, parsing, and serialization definitions as the base for further Discourse-specific features. An extension API is included to enable further customizations. The necessary extensions to support all Discourse's core and core plugins features **will be implemented in subsequent PRs**. --------- Co-authored-by: David Taylor <david@taylorhq.com>
