/**
|
|
* Postinstall script — runs automatically after `bun install` or `npm install`.
|
|
*
|
|
* Downloads ripgrep binary (idempotent, skips if exists).
|
|
* Works in dev mode (src/ exists), published mode (dist/ exists), with bun or node.
|
|
*
|
|
* Usage:
|
|
* node scripts/postinstall.js
|
|
* node scripts/postinstall.js --force
|
|
* bun run scripts/postinstall.js
