Allow regex / non fuzzy search in the file picker

[yoav-lavi]

For certain workflows (e.g. "go over every .rs file in directory xyz") it would be beneficial to be able to more strictly filter files in the file picker.

This could be done by defining a specific syntax for it (e.g. /query/ is regex, !query is exact) or using some sort of keybinding to switch modes with a UI indication of the current mode.

An additional mode or syntax could be search in files (like space+/, but in a file selection context)

Fuzzy completions already have special syntax for more exact searches.

You can use $ for suffix match, ^ for prefix match, ' for substring match, ! for negated substring match (every that contains this substring will be removed), !^ for negated prefix match and !...$ for negated postifx match.

This syntax allows what you have described. For example

^directory/to/search .rs$

I don't see us implementing a regex mode for the pickers.
