Evaluate Twinkleplop for terminal code highlighting

[sentry-junior]

Terminal Markdown code blocks use a different highlighter from the local UI, so the advertised Twinkleplop-versus-Shiki speedups do not establish a benefit here. This task tracks evaluating terminal suitability rather than committing to a replacement.

• The Markdown formatter uses cli-highlight, backed by highlight.js. That dependency renders HTML and parses it into ANSI output; Twinkleplop exposes HTML or flat token spans, not a compatible terminal rendering API.
• No direct terminal performance comparison has been run. Startup, packaged size, ANSI output, language coverage/autodetection and plain/NO_COLOR behavior remain evaluation concerns. highlight.js is absent from the published comparison.
• SQL formatting is outside this scope: @sentry/sqlish provides tolerant parsing, parameter recognition and structural formatting in addition to coloring.

opened #1634 with a written evaluation of twinkleplop for terminal code highlighting.

tl;dr — recommend keeping cli-highlight: twinkleplop has no terminal/ANSI rendering API (only HTML/token spans), its benchmarks omit highlight.js, and it isn't installable from npm so no real comparison could be run. full writeup lives at docs/superpowers/specs/2026-09-24-twinkleplop-terminal-highlighting-evaluation.md. ready for review.
