v0.2.1 - Marketplace icon

Adds a Marketplace icon drawn from the extension's own palette and set in the typeface it bundles. No functional change from v0.2.0.

v0.2.0 - bundled font

The preview font now ships with the extension. No system font install required on macOS, Windows, or Linux.

Install

```bash
code --install-extension jeff-markdown-preview-0.2.0.vsix
```

Then run Developer: Reload Window.

Changes

• Bundled iA Writer Duo S as woff2 (regular/italic/bold/bold-italic), loaded via @font-face. local() is tried first, so an installed system copy is used when present.
• The Markdown editor font still requires a system install — the editor is not a webview. Per-platform steps are in the README.
• Added MIT license, SIL OFL 1.1 notice for the typeface, and repository metadata.
