* fix: signal.SIGINT and signal() raise NotImplementedError on wasi - Problem: signal.SIGINT and friends don't exist on wasi, and signal.signal() is hard-stubbed to raise NotImplementedError there - Cause: wasi-libc emulates signal()/raise() in a separate opt-in library that Rust's own wasm32-wasip1 target distribution doesn't ship - Fix: vendor wasi-sdk's prebuilt libwasi-emulated-signal.a, link it for wasm32-wasip1, and wire SIGINT/SIGABRT/SIGFPE/SIGILL/SIGSEGV/SIGTERM, signal()/getsignal()/raise_signal() through it. CPython's own WASI build links the same library Assisted-by: Claude Code:claude-sonnet-5 Signed-off-by: Jiwoo Ahn <ikwydls1314@gmail.com> * Group WASI signal definitions in mod wasm Move WASI-only types, constants, FFI, and handlers into `mod wasm` and re-export them with `#[cfg(target_os = "wasi")]`.
