feat: multi-style pure SVG org chart renderer (no Playwright needed)

Rewrote org-chart-svg.ts to support all 5 styles (monochrome, nebula,
circuit, warmth, schematic) as pure SVG — no browser or Satori needed.
Routes now accept ?style= query param. Added standalone comparison script.

+  <h3>Why Pure SVG instead of Satori?</h3>
+  <p>
+    <strong>Satori</strong> converts JSX → SVG using Yoga (flexbox). It's great for OG cards but has limitations for org charts:
+    no <code>::before/::after</code> pseudo-elements, no CSS grid, limited gradient support,
+    and connector lines between nodes would need post-processing.
+  </p>
+  <p>
+    <strong>Pure SVG rendering</strong> (what we're using here) gives us full control over layout, connectors,
+    gradients, filters, and patterns — with zero runtime dependencies beyond <code>sharp</code> for PNG.
+    It runs on any Node.js route, generates in &lt;10ms, and produces identical output every time.
+  </p>
+  <p>
+    Routes: <code>GET /api/companies/:id/org.svg?style=monochrome</code> and <code>GET /api/companies/:id/org.png?style=circuit</code>
