Auto download/star based on a podcast title/description in the user's feed containing a previously saved string

### What problem does this address?

To save reading the description of many episodes I'd like episodes (within my feed) to automatically download or star if the podcast title or description contains a string/regex expression which I saved earlier (like a certain person's name or a company name or a specific topic)

### What is your proposed solution?

Save strings of text or regex expressions e.g. a person's name, a company. Associate an action with each string e.g. auto download/star.

When that text appears in a podcast episode's title or description then the episode will be automatically downloaded or starred (user's preselected choice)

### Did you search for existing feature suggestions?

- [X] I have searched for existing feature suggestions.

Start by reviewing the existing feed, download, and star behavior to determine where saved strings or regular expressions and their associated actions would fit. Clarify how matching, persistence, editing, and conflicts between actions should work; done means matching episodes in the user's feed are reliably downloaded or starred according to the saved rules.
