fix: use --no-verify on cargo publish to work around build.rs OUT_DIR restriction

build.rs creates a placeholder contributors.csv in the package root when the
file is absent. cargo publish extracts the crate into a clean sandbox where
the file does not exist, causing the verification build to fail with:

  Source directory was modified by build.rs during cargo publish.
  Added: .../contributors.csv

--no-verify skips this redundant verification step. The binary has already been
fully compiled and tested in the build matrix job before publish runs.
