feat: CodeMirror markdown editor for identity/memory file editor
Replace plain textarea with CodeMirror 5 + markdown mode loaded from jsDelivr CDN. Editor fills the modal body via flex layout, theme-aware via CSS vars (cursor, selection, headings, bold/em/links/code all mapped to Cortex dark/light palette). Lazy init on first file open; history cleared per-file so undo doesn't bleed across files. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
