feat(1.0.10): experimental chrome.* spoof for Google embedded-browser detection

Browse Source 
Inject chrome.app, chrome.runtime, chrome.csi, chrome.loadTimes,
navigator.permissions.query wrapper via executeJavaScript on dom-ready
for every view. Goal: pass Google's JS-side embedded-browser detector
("Возможно, этот браузер небезопасны") by exposing the same chrome.*
shape real Chrome does.

Caveats acknowledged upfront:
- dom-ready fires AFTER <head> scripts, so detection scripts there have
  already seen the un-spoofed environment. Helps only if Google re-checks
  on form submit / later events.
- TLS fingerprint (JA3/JA4) is server-side. If Google flags us there,
  no client-side spoof works. This is a best-effort attempt.

No webPreferences changes — keeps contextIsolation:true and
sandbox-equivalent isolation intact. If this fails we lose nothing
architecturally and revert is trivial.
