v5.0.1

Code playgrounds, a favicon option, and a refreshed code block.

Playgrounds (#329)

Open an @example (or a code fence) in CodePen, JSFiddle, or CodeSandbox, prefilled — bringing back and generalizing v4's codepen feature. A code block's header gains an "Open Code in" dropdown; it's fully client-side (form POST / parameterized link — no backend, no API key). Configure with opts.playground (enableForAllExamples, providers, site-wide per-provider options) and the @playground block tag (provider selection, none/off, plus filename= and highlight=). Works in prose too (a js playground fence or a <playground> container) and through both the JSDoc and TypeDoc bridges.

Favicon

New favicon option — a path to an image the theme copies to a content-hashed asset and links as <link rel="icon"> (with the right type). Restores the v4 option v5 had dropped, and is the way to ship an SVG favicon (browsers auto-discover only a root favicon.ico).

Refreshed code block

Each block now has a header bar (a CODE/filename label plus copy and the playground dropdown), per-line highlighting, and configurable code-chrome colors (codeHeaderBg / codeHeaderFg / codeHighlightBg under colors / darkColors) that stay legible in light and dark.
