fix: resolve tag:production version extraction error
- Fix grep pattern to only match root-level version field in package.json
- Prevent matching the 'version' npm script which was causing shell syntax errors
- Use '^\s*"version":' pattern to match only the actual version field at line 3
- Add head -1 to ensure only first match is used
- Fixes: echo \ /bin/sh: eval: line 200: syntax error: unexpected redirection
