Rust-native browser backend is not compiled. Rebuild with --

Error message

Rust-native browser backend is not compiled. Rebuild with --features browser-native

What it means

The rust-native action execution path was reached in a binary compiled without the 'browser-native' feature (the cfg(not) stub). Unlike resolve_backend, which gates earlier, this fires if execution still selects the rust-native path; the fix is a rebuild.

Solutions

1. Rebuild the core with --features browser-native.
2. Route the action through an available backend (playwright, agent-browser, computer_use).
