## BitLogger Update Changes

version 0.4.1

### Feature

- feat: make `bitlogger_async` compile on `js` / `wasm` / `wasm-gc` via a compatibility backend instead of abort-only stubs
- feat: add `async_runtime_mode()` and related helpers so callers can explicitly detect native-worker vs compatibility async behavior
- feat: add `AsyncRuntimeState` JSON/stringify helpers for exposing async runtime mode in diagnostics

### Test

- test: cover async logger compatibility backend queue drain behavior and keep async config roundtrip available on non-native targets
- test: cover async runtime capability helper consistency across backend-specific implementations

### Notes

- `bitlogger_async` now provides a compatibility implementation on non-native targets; the standalone async example remains `native`-only because `async fn main` entry support is still toolchain-limited
- `examples/async_basic` now prints the current async runtime state at startup so downstream projects have a minimal diagnostic pattern to copy
