ReGex匹配确切的单词，而忽略包含它作为子字符串的单词？

Question

I'd like to match all instances of prod in a large file. The file contains arrangements such as:

• prod
• "prod"
• .prod
• prod.
• prod*
• (prod
• production

I'd like way to match (and ultimately, replace) all instances of the above, except for the last result . The best I've come up with so far is just a simple \\W : https://regex101.com/r/8bOrcS/1/
