feat: add release pipeline for crates.io and npm publishing

- Add --check, --publish-crates, --publish-npm-sdk, --publish-npm-cli flags to release script
- Create CI workflow with pre-release checks (cargo fmt, clippy, test, tsc)
- Update release workflow to run checks, build binaries, and publish packages
- Add @sandbox-agent/cli npm package with platform-specific binaries (esbuild pattern)
- Configure TypeScript SDK for npm publishing (exports, files, types)
- Add crates.io metadata to Cargo.toml (repository, description)
- Rename @sandbox-agent/web to @sandbox-agent/inspector
