Vendoring complete.

To build offline using the vendored sources, run from the repo root:

  CARGO_HOME="$PWD/.cargo-vendored" cargo build --locked
  CARGO_HOME="$PWD/.cargo-vendored" cargo test --locked
  CARGO_HOME="$PWD/.cargo-vendored" cargo install --path . --locked

This avoids any network access and uses ./vendor exclusively.
