+ * Shared browser-launch and profile helpers for web-automation scripts.
+ *
+ * Centralises the three reusable primitives that every command entry point
+ * needs:
+ *   - getProfilePath()     — resolve the persistent CloakBrowser profile dir
+ *   - launchBrowser()      — launch a CloakBrowser persistent context
+ *   - getPage()            — get a ready Page + BrowserContext pair
+ *
+ * All command entry points (auth.ts, browse.ts, flow.ts, scan-local-app.ts)
+ * import from here instead of duplicating these bodies.
