chore: Remove inactive pre-commit hook configuration

[hristoterezov]

Summary

Removes the non-functional pre-commit hook configuration from package.json.

Problem

The package.json contained a pre-commit field that referenced lint and test scripts:

"pre-commit": [
  "lint",
  "test"
],

However, this configuration was not functional because:

• The pre-commit npm package was not installed in devDependencies
• No git hooks were active in .git/hooks/
• Testing confirmed commits succeeded without running lint checks

This created confusion about whether pre-commit checks were enforced.

Changes

• Removed pre-commit field from package.json

Alternative Quality Checks

Developers should:

• Manually run npm run lint before committing (as they currently must do)
• Rely on CI pipeline which already enforces linting on pull requests

Test Plan

• Verified package.json is valid JSON after removal
• Confirmed npm commands still work (npm run lint, npm run build)
• Tested that commits work normally (they already did, but now it's clear why)
