Making Rust Workers reliable: panic and abort recovery in wasm‑bindgen

Rust Workers addresses panic and abort reliability issues in WebAssembly using exception handling and recovery mechanisms.

• •Initial mitigation used custom panic handlers and Proxy-based JavaScript wrappers to contain failures
• •panic=unwind support enables destructors to run correctly, preserving instance state across panics
• •Panics surface to JavaScript as PanicError exceptions with proper async Promise rejection
• •Exception tags distinguish between recoverable panics and non-recoverable aborts
• •set_on_abort hook allows custom recovery handlers for platform-specific abort scenarios
