D-50 behavior 4: opening a renderable .md in the editor now auto-reveals the context-panel reader, which mirrors the buffer read-only and re-renders as the user types — rather than a one-shot disk read. The extension reveals the tab on editor.opened (renderable only — D-50 behavior 5 leaves non-.md files alone). The viewer owns the mirror: on mount it picks up the active buffer (editor.read, no id), enters mirror mode on editor.opened / active-changed for a renderable file, re-reads the in-memory buffer on editor.edited, and drops the mirror (with its edit affordance back) on a disk load or a switch to a non-renderable buffer.
