zowex: Use a lexer and/or parser to interpret CLI input

[traeok]

Is your feature or enhancement request related to a problem or limitation? Please describe

Currently, we parse arguments using the ZCLI::parse_input function, which iterates over the string and attempts to gather positional arguments and options. However, there are certain scenarios where the function may encounter difficulties when parsing input, e.g.:

• parentheses around the command (or parts of it)
• quoted strings
• command chaining

Describe your enhancement idea

Use an AST parser and lexer to parse input, handling complex scenarios such as the ones outlined above.

Describe alternatives you've considered

We can implement regex and more complex processing, but a lexer/parser would be a bit easier and avoid edge-case issues.

Provide any additional context

Going to assign this to myself to investigate on the side - but if anyone wants to implement something like this, feel free to add yourself as an assignee 😋
