/**
 * nicknisi Header Extension
 *
 * Replaces pi's built-in header with an animated nicknisi sitting at the
 * top-left, Claude Code style, with session info beside him:
 *
 *  - "blink" mode (default): nicknisi-blink.gif — a close-up blink loop
 *  - "waiting" mode: nick-waiting.gif — the Sonic-style waiting animation
 *    (waits 5s, taps its foot, loops)
 *  - "full" mode: the nicknisi ASCII art from the Neovim dashboard
 *    (config/nvim/lua/nisi/assets.lua), with blinking eyes
 *  - "compact" mode: half-block version of the ASCII art (muddier)
 *
 * GIFs are converted to truecolor half-block frames by gen-frames.mjs:
 *   node gen-frames.mjs <gif> <out.ts> <cols> <pxHeight>
 * (square-ish px grid ≈ correct aspect for Monaspace Neon + adjust-cell-height=10%)
 *
 * Session info: pi version + model, cwd + git branch, and a random quote
 * typed out character-by-character. Shown only on fresh sessions; the
 * built-in header is restored when the first prompt is sent — like the
 * vim dashboard disappearing when you get to work.
 *
 * `/nicknisi-header` cycles blink → waiting → full → compact.
