// Source: https://github.com/Nikolay-Shirokov/cc-1c-skills
/**
 * CLI runner for 1C web client automation.
 *
 * Architecture: `start` launches browser + HTTP server in one process.
 * `exec`, `shot`, `stop` send requests to the running server.
 *
 * Usage:
 *   node src/run.mjs start <url>            — launch browser, connect to 1C, serve requests
 *   node src/run.mjs run <url> <file|->     — autonomous: connect, execute script, disconnect
 *   node src/run.mjs exec <file|->          — run script against existing session
 *   node src/run.mjs shot [file]            — take screenshot
 *   node src/run.mjs stop                   — logout + close browser
 *   node src/run.mjs status                 — check session
 *   node src/run.mjs test [url] <dir|file>  — run regression tests
