Bump napi: re-raise guest WASI process exits (ECO-416)

[Arshia001]

Bumps the lib/napi submodule to pull wasmerio/napi#47 (317fac4).

The N-API callback trampoline now re-raises a guest WasiError::Exit (Node's fatal-exception std::_Exit on the main thread) through the N-API import layers instead of swallowing it. A guest that proc_exits from inside a host→guest callback now tears down only its own instance cleanly, instead of leaving the host event loop spinning forever. Fixes test-tls-handshake-exception on the V8-imports lane (the last V8-only parity gap in the parallel/ surface).

Cargo.lock is unchanged (making wasmer-wasix non-optional in the napi crate changes only a feature edge; the CLI already links wasix). Stacked on #6825.

Pull request overview

This PR bumps the lib/napi git submodule to pick up ECO-416 behavior changes so that guest proc_exit/WasiError::Exit raised from inside a host→guest callback is re-propagated through the N-API import layers (instead of being swallowed), preventing hangs in the host event loop.

Changes:

• Updates the lib/napi submodule pointer from 8224dc35e95f… to f3d5335f8bbc….
• (From PR description) Intended to restore correct process-exit propagation semantics for V8-imports callback trampolines, fixing test-tls-handshake-exception.
