Function execute_module 

pub fn execute_module(
    scope: &mut HandleScope<'_>,
    bridge_ctx: &BridgeCallContext,
    bridge_code: &str,
    user_code: &str,
    file_path: Option<&str>,
    bridge_cache: &mut Option<BridgeCodeCache>,
) -> (i32, Option<Vec<u8>>, Option<ExecutionError>)

Execute user code as an ES module (mode=‘run’).

Runs bridge_code as CJS IIFE first (if non-empty), then compiles and runs user_code as a v8::Module. The ResolveModuleCallback sends sync-blocking IPC calls via BridgeCallContext to resolve import specifiers and load sources. Returns (exit_code, serialized_exports, error). The bridge_cache parameter enables code caching for repeated bridge compilations.
