CHR from the shell: quickchr CLI + centrs

quickchr (@tikoci/quickchr, CLI + Bun/TS library) downloads a MikroTik CHR image, boots it under QEMU, and hands you a router. This skill is the shell-first path: you have a terminal, you want a router to interrogate, and the answer will be quoted as shell + RouterOS commands (e.g. in a forum.mikrotik.com reply). If you are writing a bun:test harness that imports QuickCHR, use the routeros-tikoci-quickchr skill instead — one scheme per task, never both.[^split]

Behavior below is pinned to 0.5.2. Install with bun install -g @tikoci/quickchr@0.5.2, or invoke bunx @tikoci/quickchr@0.5.2 <command>. Check yours with quickchr --version. Where 0.4.8 and earlier differ in a way that can hurt you, the text says so inline; the rest of the version history lives in the footnotes.[^pin]
