/**
 * browser.ts — Playwright browser launcher for cv jobs apply
 *
 * DESIGN PHILOSOPHY (browser-use methodology):
 *
 * We NEVER try to use the user's real Chrome profile while Chrome is running.
 * Chrome locks its profile directory — any attempt to `launchPersistentContext`
 * against a locked profile causes a SIGTRAP crash, which is the root cause of
 * all previous failures.
 *
 * Instead we use ONE strategy, always:
 *   - A DEDICATED automation profile at ~/.careervivid/browser-session/
 *   - This is a persistent Chromium profile separate from the user's real Chrome
 *   - It persists cookies, localStorage, and login sessions across runs
 *   - The user only needs to log in to each ATS once; subsequent runs are instant
 *   - It uses the real Chrome binary (best site compatibility) if available
 *   - It is NEVER locked because we control its full lifecycle
 *
 * After launch, the caller is responsible for navigating to the target URL
 * via page.goto(). The browser starts at about:blank.
