I bumped TypeScript to the 7.1, which only needed a typing fix in wasm for the new WebAssembly.compile DOM signature, the emitted .d.ts files are unchanged, and I dropped the leftover ts-node config while at it.

Benchmark

Not faster in terms of time, but more memory efficient on average.

tsc --noEmit on every packages/*/tsconfig.json, median of 5 7.0.2 7.1.0-beta
total time 6.06s 5.98s
avg peak memory per package 139 MiB 115 MiB

I'm waiting on final release, currently it is in beta.

ts-node is no longer installed; tsx replaced it. The nextjs tsnode tsconfig was identical to its regular tsconfig.
The 7.1 DOM lib widens the WebAssembly.compile source parameter to AllowSharedBufferSource, so the wasm patch now derives its parameter type from WebAssembly.compile.
