fix(ci): build tarball filename from package.json to avoid oclif warn… …ings The previous approach using 'pnpm pack --json | jq -r .filename' was fragile because oclif warnings would contaminate the JSON output, causing jq parsing to fail. Now we construct the filename directly from package.json using the standard npm naming convention: <name>-<version>.tgz. This makes the workflow more robust and independent of pnpm's output format. Changes: - Extract name and version directly from package.json using jq - Transform scoped package names (@org/pkg -> org-pkg) - Construct filename following npm conventions - Use 'pnpm pack --silent' to suppress unnecessary output
