docs: reposition Cortex as a scientific-authoring tool, not just memory+graph

The current README positions Cortex as memory + neural graph. After
Phase 2-10 of the wiki redesign, it's also a first-class scientific
authoring environment — CodeMirror editor, KaTeX math, BibTeX
citations, Pandoc export — and readers weren't picking that up.

Two changes:

1. New "Write papers in Cortex" section near the top of the README
   (right after Getting Started), with the edit-mode split-pane
   screenshot as the headline visual. Enumerates the authoring
   capabilities in scannable form.

2. Enhanced "Wiki View" subsection in the Views section — bulleted
   feature list (heat bar, lifecycle pill, inspector, editor,
   citations, export) that mirrors the top-section narrative and
   links back to it.

TOC updated with the new anchor.

+## Write papers in Cortex
+
+Cortex doesn't just remember — it authors. Every memory that passes the pipeline becomes a structured wiki page, editable in place with a full scientific writing environment:

+
+- **CodeMirror 6 inline editor** with live preview; save round-trips atomically to the `.md` file on disk (git-diffable).
+- **LaTeX math** — `$E=\nabla \cdot F$` and `$$…$$` blocks rendered live via KaTeX.
+- **BibTeX citations** — drop `.bib` files under `wiki/_bibliography/`, use `[@friston2010]` inline, and Citation.js resolves them to `(Friston 2010)` with an auto-generated APA bibliography.
+- **Figure / equation / table auto-numbering** — `{#fig:arch}` labels, `{@fig:arch}` cross-refs, resolved to `Figure 1` / `Equation 3` / `Section 2.1`.
+- **Pandoc export** — one click produces PDF (via LaTeX), TEX, DOCX, or HTML. Journal-submittable from the same markdown that feeds the memory pipeline.
+
+The source stays markdown. Your `.md` files remain grep-able, diffable, and interoperable with any external tool. Cortex adds a rendering + editing + export layer on top without stealing your content into a proprietary format.

 ## What this actually feels like
 
 **Monday.** You spend an hour debugging a webhook handler. After tracing through four layers, you find the root cause: a race condition in the Redis session store where TTL expiry can fire between the auth check and the permission lookup. You discuss the fix with Claude, decide on an approach, and implement it. Session ends.
