Fix npm publish package paths

[alphaqiu]

Summary

• publish npm packages using explicit local paths: ./npm/ok-darwin-arm64, ./npm/ok-darwin-x64, ./npm/ok
• prevents npm from interpreting npm/ok-darwin-arm64 as a git package spec

Root cause

Release #3 failed because npm publish was invoked with npm/ok-darwin-arm64 without ./, so npm attempted git ls-remote ssh://git@github.com/npm/ok-darwin-arm64.git and failed with Permission denied (publickey). This is not an NPM_TOKEN issue.

Verification

• ruby YAML parse for .github/workflows/release.yml
• git diff --check
• rg -n 'npm publish' .github/workflows/release.yml
