Move swc-playground-wasm into workbench/swc-playground (#1704)
1f08cbf 
* move swc-playground-wasm into workbench/swc-playground

Move the Rust/WASM source from packages/swc-playground-wasm into
workbench/swc-playground/wasm/ so it is no longer built as part of
the packages/* turbo filter in CI. The WASM build now runs as part
of the playground's own prebuild/dev scripts, avoiding Rust toolchain
failures in unrelated CI jobs.

* fix: ensure default rustup toolchain in wasm build

The Vercel build environment has rustup installed but no default
toolchain configured. Add a check for this and install stable
if needed. Also check for VERCEL env var in addition to CI.

* fix: ensure cargo bin dir is in PATH on Vercel

After cargo install wasm-pack, the binary lives in $CARGO_HOME/bin
which may not be in PATH on the Vercel build environment. Always
add the cargo bin directory to PATH after ensuring the toolchain.
