* feat: support wasm32-wasi as a production target - Add production LLVM WASI codegen with a 32-bit ABI, coroutines, and dynamic modules - Integrate WASI builds and execution into the CLI with capability diagnostics - Add differential coverage and document the fourth production target Co-authored-by: Albert <57402359+bulatovv@users.noreply.github.com> * fix: address wasm target review findings * fix WASI guest paths and fetch alias detection * fix WASI async bridge and fetch detection --------- Co-authored-by: Albert <57402359+bulatovv@users.noreply.github.com>
