Use exact dependency versions

Always specify exact dependency versions in package.json files instead of using version ranges (^, ~) to ensure reproducible builds and prevent accidental upgrades that could introduce breaking changes.

When adding new dependencies or updating existing ones, pin to specific versions to maintain build consistency across environments. This is especially important for production applications where unexpected dependency updates could cause runtime issues.

Example:

// ❌ Avoid version ranges
"dependencies": {
  "snap-shot-core": "^7.4.0",
  "diff": "^4.0.1"
}

// ✅ Use exact versions
"dependencies": {
  "snap-shot-core": "7.4.0", 
  "diff": "4.0.1"
}

Remember that configuration changes may require additional dependencies - for example, enabling "importHelpers": true in tsconfig.json requires adding tslib as an exact dependency. Always verify that configuration changes don’t introduce missing dependency requirements.
