Subject: [PATCH] chore: apply rustfmt and silence wit-bindgen clippy lint

CI runs cargo fmt --check and clippy with -D warnings. Two issues
needed addressing before the first PR could go green:

- Source had drifted from rustfmt output (single-call vec!, fluent
  builder chain on one line, etc.). Apply 'cargo fmt --all'.
- modules/example: wit_bindgen::generate! expands to host-import
  shims whose arity matches the WIT signatures, exceeding clippy's
  too-many-arguments threshold. Allow the lint at crate level with
  a comment explaining the source.
