Runs as a WebAssembly component without JS or WASI

Changelog

Feature BashkitCode

In Bashkit 0.17.0

Docsbashkit#2311bashkit#2310

Bashkit can now run as a WebAssembly component that exposes shell execution over WIT, in a host with no JavaScript engine and no WASI implementation. That covers plain wasmtime and the no_std wasmtime that hyperlight-wasm compiles into a Hyperlight micro-VM guest. examples/hyperlight/ builds such a guest and runs a script through it.

Dependencies that assumed a JavaScript host, such as the clock, timers and entropy source, moved behind a new wasm_js feature that the JS packages enable and other builds leave off. The bashkit crate also builds for wasm32-wasip2, checked in CI.

See the Hyperlight example, #2311 and #2310.
