Audit and remove unused dependencies

[daedalist]

Effort: Medium (1-2 hours)
Impact: Smaller bundle, faster installs, better security
Phase: Long-Term

Current State

Some dependencies might be transitive or unused (node_modules: 557MB)

Dependencies to investigate

• @eslint/eslintrc - may not be needed with native flat config
• Testing libraries if not writing tests
• follow-redirects, node-forge, nth-check - verify if these are direct deps or transitive

Pros

• Smaller node_modules (currently 557MB)
• Faster installs
• Reduced security surface area
• Cleaner package.json

Cons

• Need to verify each isn't needed

Risks

Low - can always add back if needed

Implementation

1. Use npm ls <package> to check if dependency is used
2. Use depcheck tool to find unused dependencies
3. Remove candidates one at a time
4. Test build and functionality
5. Commit changes
