style(site): JSDoc tags stay prose-sized but dimmer; highlight meander @example code

Two follow-ups from the previous annotation-prose pass:

1. The @tag markers were too small + monospace — read as UI
   chrome, not inline prose. Drop the mono family + 0.88em
   size; keep only `color: var(--muted)` so the tag reads at
   the same weight and rhythm as surrounding text, just
   dimmer (it's metadata, not loud).

2. Code blocks inside @example fences rendered plain because
   meander hydrates them without a language- class, and our
   global hljs init skips those to avoid auto-coloring random
   text. cleanupAnnotationProse now runs hljs.highlightElement
   on every <pre><code> inside .annotation-md. Auto-detection
   is safe here: the content is always code by the JSDoc
   contract, so the "plain-text mis-coloring" concern doesn't
   apply.
