SRVOCF-946: Add Husky pre-commit hook with lint, type-check, and Go checks

[Cragsmann]

Summary

• Add Husky pre-commit hook that runs yarn lint:fix, tsc --noEmit, and go vet/gofmt on backend/
• Add type-check and prepare scripts to package.json
• Add skipLibCheck: true to tsconfig.json (prevents false positives from third-party type declarations)
• Hooks auto-install on yarn install via the prepare script

Test plan

• yarn lint:fix passes
• yarn type-check passes
• Go vet and gofmt pass on backend/
• Pre-commit hook runs successfully end-to-end

Looks good! Thank you for this. 👍

One thing. Can you use our commit message standard?

Please use the commit message slash command or the commit message guide to craft a brief commit message using conventional commits spec.

What do you think about adding a commit lint to the pre-commit hook too in a follow up PR?
