Struct WarmIsolatePool 

pub struct WarmIsolatePool { /* private fields */ }

Configuration holder and factory for pre-warmed JS extension runtimes.

Since PiJsRuntime uses Rc internally and cannot cross thread boundaries, the pool does not hold live runtime instances. Instead, it provides a factory that produces pre-configured PiJsRuntimeConfig values, and runtimes can be returned to a “warm” state via PiJsRuntime::reset_transient_state.

Lifecycle

1. Create pool with desired config via WarmIsolatePool::new.
2. Call make_config to get a pre-warmed PiJsRuntimeConfig for each runtime thread.
3. After use, call PiJsRuntime::reset_transient_state to return the runtime to a clean state (keeping the transpiled source cache).
