Socket.dev recommendations

We should include recommendations for how to use Socket.dev. These recommendations may be relevant to a number of different workflows (e.g. repository setup, PR status checks, guidelines for adding dependencies, security audits, etc.) so we may want to embed these recommendations in multiple articles.

Start by reviewing the contributor documentation articles covering repository setup, PR status checks, dependency guidelines, and security audits. Identify which articles should include Socket.dev guidance and define done as updating the relevant articles with agreed recommendations; the issue names no specific files or tests.
