Window -w argument by id or name

[bdupras]

This PR adds the option to specify windows by name when using the -w argument. (I also considered adding a separate -W argument.)

Argument -w matches windows by id or whose title starts with the given string (case-insensitive). If multiple windows match, the window with the lowest ID is selected.

chrome-cli list tabs -w Gmail
chrome-cli list tabs -w "2025 Reports"
chrome-cli close -w GitHub

Also adds a chrome-beta-cli wrapper script for Chrome Beta (com.google.Chrome.beta).

Thanks for this tool @prasmussen! Very cool. I hope you like this contribution - and happy to incorporate any feedback.

Also a quick disclaimer that I'm not experienced with Objective-C and this code was mostly created with AI assistance. If you think it's not correct or not idiomatic in any way, I'm happy to refactor as necessary.
