[FR] Add support for regex patterns in exclude

[MarArMar]

Is your feature request related to a problem? Please describe.
I want to exclude /node_modules/ and /.venv/ from my searches (installed libraries in software projects)

Describe the solution you'd like
In the exclude, accept regex patterns

Describe alternatives you've considered
Listing all my modules folders but there are many

[MarArMar]

Ah can I just do this like "node_modules;.venv" ?

[MarArMar]

Linked to #564

I would like to be able to input paths like /run/ because I cannot do it otherwise

It could also be able to support path patterns fore example **/.bun/install/cache/** and **/.local/share/** and **/.config/BraveSoftware/** would be really useful to me

Yes, more flexible exclude patterns are planned. I've also been experimenting with a better UI for that, where for each exclude entry you can specify its scope (file, folder, name, full path) and the pattern type (regex, wildcard, literal).

Together : Regex + manual input of paths would enable many use cases

In my case I would exclude all modules/libraries folders, even those that I have not created yet, with patterns

Currently because I cannot exclude easily (too many folders to exclude in many places and I create new ones regularly), I just index all files in my filesystem (millions)
