test: add comprehensive CLI test suite

Add 56 test cases across 4 test suites to verify the yue command line
tool functionality:

- Basic options test: -h, --help, -v, --version flags
- Compilation test: file/directory compilation with various options
- Error handling test: syntax errors, file not found, edge cases
- Execution test: -e option, script arguments, macros

The test framework includes helper functions for assertions and test
environment setup. All tests can be run via `bash spec/cli/run_all_tests.sh`.
