refactor(docs): remove CSS/SCSS/SQL/SH/Svelte from docs parser

These file types are not documentation - they are code that was
incorrectly classified as docs. Removing them from the docs parser:

- SQL: query language
- SH: shell scripts
- Svelte: frontend framework components

This reduces docs from 551 to ~49 files on the barou Laravel project,
making the language sort put PHP/JS first and dramatically reducing
indexing time for documentation.

Updated tests to verify these extensions are no longer handled by docs.
