v0.6.13

Fixed

• Suppress Chrome's extra startup window using stock --no-startup-window, preserving headless defaults and composing caller launch arguments. URL-less open now uses native lazy URL reads so active pages keep their browser, profile, and URL across direct, batch, and script calls. External engines and attachments remain unchanged.

Changed

• Give ordinary browser calls a native session and restore key per root Pi session. Parent/descendant groups share one browser without a global queue or child-exit teardown. Scope named Chrome profile bootstrap to automatic roots; preserve explicit browsers, script, and Electron isolation.

Validation

• Start managed-lifecycle release checks explicitly in fresh mode; retain root-session ownership without leaving test browsers open.
