## Summary
- Tagged fenced code blocks (```js ... ```) now emit Telegram's
`<pre><code class="language-js">` form instead of leaking the language
token into the code body
- Untagged fences stay plain `<pre>`; single-line ``` ```code``` ```
fences become inline `<code>`
- Fixes#6602
## Test plan
- New vitest cases in `telegram-html.test.ts` (tagged/untagged/inline
fences)
- Verified standalone via `node --experimental-strip-types`
