Special characters trailing issue

It seems that the PR to fix the slash as a trailing character of the URL didn't fix the issue:

• #756

I have a URL that ends with parenthesis:

https://en.wikipedia.org/wiki/Tree-sitter_(parser_generator)

And the closing parenthesis is not recognized as part of the URL.

The fix is to add all special characters or refactor the whole RegEx.

Potential fix using existing solution:

\b(?:[\/()[\].,;:!?']+)?

Also note that in hash you can put anything. I use a JSON array to keep the state in one of my websites.

Maybe it's worth using AI to create a full regex. Or use a library that is proven to work. It's also worth adding some tests to verify that the regex works correctly.

As for hash, I would just accept every non-space. Another option is to expose the regex to the user in the option (with the current default value) so the user can change it.

I can help create a PR if you're ok if it will be written by AI (of course, tested).

Start by locating the URL-matching regex and the change from issue #756, then inspect how URL parsing is tested. Add regression coverage for URLs ending in a closing parenthesis and hashes containing non-space characters; done means both examples are recognized as intended without breaking existing URL cases.
