feat: add string utility functions and decision condition tests

- Add cut_to_file() and cut_space() utility functions for file processing and field extraction
- Add comprehensive E2E tests for decision condition routing with function/command execution
- Add test workflows for decision conditions and inline decision execution
- Add short-mode skip guards to all cloud E2E tests to allow quick test runs
- Register new functions in constants and goja runtime
