Seek alternative package lookup system

[lukehinds]

Within the current version, we leverage the users selected large language model to extract package / module / library names from code snippets. While this was a good approach for our first version, it maybe worth considering other options, as a level of overhead comes from the large language models processing times. When combined with embeddings and vectorization, it appears it has a noticeable impact on performance within the users path / experience.

In the previous prototype , tree sitter was used, but the library is lacking support for wide library coverege, so a different approach maybe required.

This Story is to allow research over alternative approaches, proof of concept to demonstrate a notable performance improvement and then implementation
