test: Update tests to reflect shell quote handling

- Remove now-redundant bug reproduction test after fix verification
- Update CLI tests to use shell-native syntax without escaped quotes
- Add comprehensive edge case tests for multiword parameters
- Document parser limitations with ignored tests for quote stripping
- Update comments to clarify shell vs parser quote handling behavior
