Subject: [PATCH] fix(1.0.6): strip Trusted Types CSP on YouTube/Google to
 unbreak adblocker

YouTube response sends Content-Security-Policy: require-trusted-types-for
'script' which blocks the cliqz adblocker's inline-script injection used
to neutralize YT's anti-adblock detection (52 "HTMLScriptElement was
directly modified and will not be executed" console errors).

Strip require-trusted-types-for and trusted-types directives from CSP
and CSP-Report-Only headers for youtube.com / youtu.be / google.com /
gmail.com (and subdomains) via onHeadersReceived on all 3 sessions.
Other CSP directives stay intact so site-level security boundaries hold.
