Replace the local substring matcher with the adblock-rust engine exposed through the dedicated content blocker Rust FFI. Keep the previous engine when a replacement list cannot be parsed. Pass shared list buffers directly into Rust instead of building a duplicate C++ vector of lines first. Generate cosmetic CSS through the Rust matcher, including generic class and id selectors collected from shadow-including descendants. Keep a supplemental index for generic cosmetic selector-list rules. adblock-rust indexes these rules under the first class or id token only, so also key them by later simple class and id selectors in the list. Update ContentBlocker coverage for rule options, exceptions, third-party checks, blob and file URLs, invalid list replacement, filtering toggles, cosmetic CSS, and generic selector-list cosmetics.
