Turbopack: Rename crates/napi to crates/next-napi-bindings and update crate name (#89314)
Disclaimer: This PR is entirely claude+opencode generated.
- Crate name said `next-swc-napi`, which was confusing, because this has a lot more than swc bindings nowdays.
- The crate name didn't match the directory name, which often confused agents.
This does not change the npm package name, as that would likely have a much larger blast radius, and could break more things, to a point where it may not be worth it.
